Hide buttons if there are no windows.

[mathematicalcoffee]

Feature request - hide the buttons if there are no windows (NOTE: distinguish between 'no windows' and 'no visible windows' ?

i.e. should buttons be hidden if all the windows on the current workspace are minimized ('no visible windows'), or should they show unless there are no windows at all on the current workspace ('no windows')?

Opinions?

Various requests noticed in comments.

I think I can implement these requests by only showing the window buttons on certain occasions, which will constrain how the user may use them.

Show buttons:

• All the time, including when there are no windows. In which case clicking does nothing.
• [DEFAULT] all the time, except hide them when there are no windows.
• all the time, except when there are no minimized windows (however this will make it hard to restore a window if all of them are maximized, perhaps I should exclude this...)
• only when the current window is maximized (and controls will only affect the current (maximized) window)
• only when there are maximized windows (this will emulate the old onlymax + hideonmax behaviour: we prioritise controlling maximized windows and if we don't find any, will control the current window)
• ... more?
