Java Driver
please create a driver for java, so that it would be able to create a android frontend to accdb-databases

The error object should be expanded to included properties which can reveal the procedure, module, and object that the error is taking place in.

Right now the size is not big enough in many cases depending on the number of records. Since datasheets are usually wide anyway, this can be easily increased.

On many forms I create, I include filtering fields at the top of the form, a filter and clear filter button and the datasheet below. If the user unclicks the filter on the datasheet, this causes issues as the filtering on the form above is not cleared at the same time because the main form does not know about the "unfiltering" below. If the datasheet view had a property that controlled the "filtered" button option. If disabled, just show the word filtered if it has been but not clickable.

Several SQL Server / ODBC data types poorly supported. I have just found that NVARCHAR(MAX) is the recommended SQL Server memo field type but Access is inconsistent in handling this - text larger than 4000 characters fails to update.

Idea here is, that you should be able to turn text a) not only top to bottom but also b) flipped and c) bottom to top

Currently, if a user has Access running, much of what is meant to be secured can be accessed from another program, e.g. Excel, via Automation. This is not good.

I have always wanted to be able to add appointments to Outlook via the link to the PST file using an append query.

Let's call it something like "Concat". It would concatenate values in a field instead of summing them.

Take this query:
SELECT Product, Concat(Color) FROM ProductColors GROUP BY Product. The result might be something like this:

Flag Red, White, Blue
Tractor Green, Red

It makes it much simpler to create applications if 254 column restriction is not applied like in Access. Unfortunately in Engineering system I can't avoid using more than 254 columns. Computer speed is not anymore a problem so why to have that limit.

Please add the capability to call stored procedures in a remote ODBC database with DAO, like it existed in the past with ODBC-Direct-Workspaces.
Pass-Through-Queries are only a kludge because parameters have to be concatenated into the sql string.

With MsgBox, we can process vbYes, vbNo and other built-in choices ... it would be nice to be able to have 3 custom choices ... ie: vbCustom1 and vbCustom1Caption, vbCustom2 and vbCustom2Caption, vbCustom3 and vbCustom3Caption,

Please design a wizard for dns-less coonections to SQL databases. Make it easier to use Access as frontend devolpment for different situations.
Other RAD tools have this already.

When designing queries, it would be nice if Ctrl-Spacebar could be used (as in VBA) to pop up intellisense when typing expressions, criteria, AppendTo, ...

This is not new ... just missed! We used to be able to show the Property Sheet and Field List at the same time ... I miss this a lot!

When multiple forms are open and you go into the VBA IDE and then switch back to the GIU view, the object that was selected is no longer selected or the object that thew the VBA error is no longer selected. Furthermore, you can't just select the object from the tabs. You first have to select another object before you can select the one you want.

Please add a standard way to backup your tables to an external database ( file or SQL) on time or in the case of a certian event.

Currently this can be made visible programmatically from an external program via Automation.

Should be able to have a property for controls that can highlight when mouse passes over other than a button. Similar to Windows 10 Start menu or other Windows menus. This should also be allowed for a single row on a continuous form. Perhaps this could be a property in conditional formatting.
