MRU open files/tabs switcher (like Alt-Tab in Windows, Ctrl-Tab in Opera). By default mapped to Alt-A (another popular assignment is Ctrl-Tab).
changes since 0.7.4:
Work around implemented for bug in IDEA which caused TabSwitch to display closed files in its list oo.
Made TabSwitch usable again for people who like to set the tab limit to 1. Tab limit of 1 is automatically detected and the number of files displayed in the popup is controlled by the "recent files limit" editor setting.
Added feature to quickly switch between two tabs (Thanks to Marc Juul Christofferson). This is a new SwitchBetweenTwoTabs action, which can be assigned a key.
