Web browsers have great feature: when CTRL+W in single tabbed window is pressed, it closes the window. I think it would be very convenient to implement this simple feature also in WinMerge.
I use mouse hotkey binding to either close tabs or exit program with mouse button. The problem is, with mouse hotkey binding software I cannot detect if there is only one tab opened in tabbed interface to switch key to ALT+F4 exit hotkey. So I have to chose between CTRL+W or ALT+F4, instead of merging both features in CTRL+W hotkey, which would also exit WinMerge if there is only single tab opened.
Please either implement this feature or provide at least option to close application in case CTRL+W is pressed when only one tab is opened. Thanks.
