Please describe the problem:
I have a panel in the right with only a 'window selector' and if there is more than 7 windows open, then the panel will be hard to unminimize a window and will group new windows in a new column, instead of 

Panel options:
auto_hide = True
auto_hide_size = 0
enable_animations = False
expand = False
hide_delay = 0
orientation = Right
size = 204
unhide_delay = 0
y_centered = True

If there are 7 windows open will look like this

will 8 windows

we can see that a new column is added after the 7 window, but it shouldn't because there is space for lots more windows.
