Field description

Description

I tried to search if anyone had already proposed this, but I couldn't find anything. In case this has already been mentioned, please excuse me and delete the thread.
It would be veeery nice if there was the possibility to add a description to the various fields we create, so as to make everything easier to understand without having to dwell on the names of the fields themselves (mine have become very very very long). Finally, it would be even more beautiful if these descriptions written by us appeared later when we place the pointer on the relevant fields.
In the hope of having explained myself, I still post some screenshots of what I mean (LibreOffice Base).
Thanks in advance to all!

Is your feature request related to an issue? Please include the issue number.

I don't think so because I didn't find anything...

Does this feature exist in another product or project? Please provide a link.

Yes, it does: LibreOffice Base.

Do you have a screenshot? Please add screenshots to help explain your idea.

No source files, tests, or entry points are named in the issue. Start by reviewing the requested LibreOffice Base behavior and locating the field/schema editor and tooltip-related entry points; clarify how descriptions should be stored and displayed, then define tests for persistence and hover text.
