Support grouping for selected panel items
Items can be put into a list by the means of the dialogue “Panel Preferences” so far.
Some users configure panels for the usage of multiple rows. This setting triggers consequences for the space allocation by selected widgets (or plugins).
There can be items displayed which are represented by icons. The space below such icons (in a horizontal configuration) is kept free (for a while).
I would like to put widgets into additional rows accordingly. I suggest that they can be arranged into groups.
This layout option would reduce unused space in the graphical user interface.
