I am wondering if it is possible to resize the left panel in lighttable to my needs:
make the collections/folder panel taller as there is plenty of space underneath the image information (see #1 in attached screenshot)
make the whole left panel wider. See #2, this is the widest possible setting of the panel. It is not possible to expand it anymore. I use a 4k monitor so it should be no problem with the appropriate space.
You should be able to hold Ctrl and scroll your mouse to increase the height of the collections module. As for the panel size that might need a code change.
