Voted and would also like to add, please give some love to the TabControl. For example, allow theming and multirow tabs at the same time.

@Nigel, can you please elaborate what you meant in this request?
I use Anchoring for multiple controls, if you need multiple controls to size rather than just the one to fill the space, you can create a stacked arrangement of the controls and manually set each control to stretch in the direction you wish. As part of the same arrange they will distribute evenly.
As part of us designing on a new Linked Table Manager dialog, we are incorporating related suggestions and requests made in UserVoice and other forums.
