Given that all custom tables are now shows as tabs, the drawer shows at most 4 or 5 tabs depending on the resolution. However, while working on that, it would be very efficient if the size of the drawer can be adjusted by user so we can drag and make it wider to show more tabs by default - not have to click on the 3 dots and then click on the tab.
The status of this idea was out of date. It is now possible to resize record drawers by clicking and dragging the left edge of the drawer.
