Window control by section

[dennmuel]

Is there a specific reason, why the hex win_id values needed e.g. for moving and deleting windows are gathered via the section (quadrant / current position on the monitor) and not by the primary db-key?

It seems to be quite easy to produce a state, where a new and an existing window would have the same section value:

1. Add two windows. (id=1 has section=1 and id=2 has section=2)
2. Switch their sections. (id=1 has section=2 and id=2 has section=1)
3. Delete one window. (E.g. there's now only id=2 with section=1)
4. Add a new window. (Now there's id=1 with section=1 and id=2 with section=1)

Ultimately, I think it comes down to assigning id and section individually and not derive them from the same value as it's currently happening: https://github.com/UB-Mannheim/PalMA/blob/master/control.php#L273-L279

Still I haven't understood, why all the window controls work via section (called "window" in the request) and not id in the first place.
