[Change request] Make the screen buttons work as toggle

[n0kn0k]

Hi Hubert,

Can you make the upper "screen" buttons work as an On/Off toggle.
It would be nice to be able to quickly click through the research, reports,
diplomacy and war map every turn without having to move the mouse over half the screen to press "Close" or "OK".

That's the eventual plan, just haven't got around to the final implementation yet but I'll get there [:)]
