Ahh, thats very helpful, thanks.
There should actually be more space available on my specific linux distribution, since the panel is actually smaller (or around the same size, not sure) then it is on Windows. (This varies from distro to distro), so I'm not sure whats going on there.

There is also a maximize button in my case:
It just does not seem to do anything for me, likely because of the minimum window size.
Decreasing the minimum windows size should fix this regardless of anything, thanks again!
