Relation editing: Merge "blue" and "yellow" highlighting in the forms

[ojeker]

It is very confusing to have two ways to highlight / select things in the forms. Merge if possible.

That's how the attribute table form view works as well. The yellow highlight marks the selection, the blue the index:

What could be possible improvements? Should the index be marked differently. Like with an indicator instead of a highlight? Any ideas?

Indicator idea. Just for the discussion.

Those checkboxes never containing a checkmark but yellow inside, are maybe not needed then anymore. Yellow should stay the color of the selected features. So we might can mark them yellow (instead of blue) - but I'm not sure if it's too noisy then...

I think if the checkboxes would have a check-mark instead of becoming yellow it would be more clear that this items are "checked" for link/unlink/... The "yellow check" is typical in QGIS but was for example confusing me as a newcomer.
Changing the blue color to something else could be problematic as it comes from the theme and in unfortunate combination with the foreground color could make the text unreadable.

I agree with @domi4484 - having a check-mark may imrove the situation to make it clearer that this is about "selection".

Maybe once we could create prototypes based on the upcoming linking relation editor.
