I know that this idea has been floated twice before and I also note that the Access team have responded and indicated that this is not part of the development and I also note that its been closed so more votes cannot be taken on it. Thought it was important to re-open because its actually quite a popular idea. I understand that SQL Server / SQL Azure or SQL Express are the way to go if users are wanting larger backends but for quick and dirty working for ETL projects or random data analysis of large datasets individuals may not wish to have the additional overhead of enterprise grade backend database install. Remember a basic SQL Server install will require SSMS and the SQL engine ontop of Access - For individuals in large organisations this may require petitioning central IT for a number of weeks or months. I would always recommend using SQL as the backend for even smaller projects but increasing the max file size would just make Access even more flexible. Anyway keep up the good work MS

Give us the ability to request a partial Compress & Repair at the table level within an opened database.
It should not be impossible to compress database records and disk pages at the table level, bypassing and freeing up any space no longer needed for deleted data records and index entries.
Given Microsoft refusal to consider revamping the database Access database files to allow for larger databases, then giving us the ability to better manage the available 2GB of space by making incremental requests to compress & repair thins partially at the table-level could be a meaningful compromise. This could allow us to enable "paging-style" approaches with which to attack larger data files and import/export tasks which are presently beyond the reach of MS-Access databases.

We have a webservice on which we have a PowerApp connector that enables PowerApps to run any macro, vba procedure/function, opening of a form to fill in text-fields and/or perform the equivalent to buttonclick-events in an Access Application. If MS-Access out of the box could configure and enable a webservice on the machine it's running and thus would enable a PowerApp to be a cloudfirst/mobilefirst frontend presentation layer, MS-Access 2019 would really become something new. When the Access application has linked SQL-tables to SQL-2016 or up, it can easily delegate the creation of JSON to SQL-server, but I wouldn't be surprised VBA already has JSON functionality in Access 2019.

Access needs a quick way to get a good solid installation of Back-end and Front-end databases including a registry edit for Trusted locations and versioning.
It should also include the ability to:
Add Icons,
Add Desktop and other shortcuts,
Allow user to accept an ELUA (End User License Agreement)
Run simple scripts,
Install with full windows trust. (maybe with a certificate?)
An uninstaller.
A check for updates function.
Install support files into specified folders.
Read simple system values and react accordingly (eg if 64bit systems then install 64 bit ODBC Driver)

Also it would be nice if it could notify the user of a new application Version (via a Web ini file or similar?)
Optionally install the Access Runtime.

This would lead to massive time saving for developers and make installations quick and identical across many users...

'~~~~~~~~~~~~~~~~
VBA Native line numbering
'~~~~~~~~~~~~~~~~
Adding line numbers is something that is a pet peeve. Line numbers should be Native and error trappable by default without having to add them manually.

'~~~~~~~~~~~~~~~~~~~~
VBA Accessible Call Stack
'~~~~~~~~~~~~~~~~~~~~
A way to read from the call stack, function/sub names in order accessed, times accessed...etc

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
VBA Custom Toolbars to allow custom Macro/Function Calls
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If I could add my ow custom functions as a toolbar button and have my toolbar exportable and importable for others to use. As opposed to a full Add-In.

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
VBA button and/or right click to open SQL Editor
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Frequently I need to use an SQL editor to evaluate or build a SQL String and it takes time clicking through to a query then changing that over to an SQL editor screen.
This could be eleviated with a quick access button or right click method from ANYWHERE. Almost any commandbar could benifit from this added functionality.

'~~~~~~~~~~~~~~~~~~~~~~
VBA Higher Level Access
'~~~~~~~~~~~~~~~~~~~~~~
What I mean by this is a way to look down over the project as a whole. Functions such as onDatabaseClose() or countAllOpenExternalConnections().
Another use would be a public onOpen(byval ObjectName as String) Event that fires for all objects of a certain type. So Before a form opens and runs it's own onOpen event you
could run a higher level procedure to capture or set data without having to add any code at all to the forms onOpen Procedure. Obviously it would know very little about the
object being opened but none the less I can see uses for such a procedure.
....and more that I can't think of this second...

'~~~~~~~~~~~~~~~~~~~~
'Access Forms ListBox
'~~~~~~~~~~~~~~~~~~~~
A more robust Listbox, Native and with the ability to add icons and check boxes, colours,buttons,editable textfields, sort orders.
Sure you can add an ActiveX component but why not Native? Improve this usefull feature.

'~~~~~~~~~~~~~~~~~~~~~~~~~
Access Tab Controls
'~~~~~~~~~~~~~~~~~~~~~~~~~
Should be able to have tabs aligned horrizontally as well as vertically

'~~~~~~~~~~~~~~~~~~
more to come when I think of them.....

Hello Team,
A mobile app developed using MS-Access itself can help in creating Apps which can be used by a Sales Team which is performing marketing activities in remote locations.
The mobile app can help the Sales person record the customers enquiry (Very minimum fields) and on a push of a button have it flushed to the Corporate CRM database.
I'm asking for a Small Mobile App development tool which can help MS-Access run on any mobile (I'm speaking of a very very light version).
This will not only make MS-Access a versatile product but millions of mobile app developers can switch their current mobile app development tool and start using this one.

This mobile app can help thousands of MS-Access developers add more value to their current products to integrate islands of remote data.

Will truly appreciate if the team adds this feature to make the product even more stronger.

Thanks in advance.
