Data builder - add collapsible functionality for data table overview

Please in the Data builder add collapsible functionality in the data table overview table. This would help to keep the overview tidy, by possibility to group certain tables.

Thanks for considering

It would certainly help my brain keep things straight if I could put different parts of an app in separate groups or folders. I have an app that does several different functions and requires many different tables. After about 8 tables it starts to get a bit unruly and jumbled. A collapsible group or folder per function would be most helpful.
