oh, what a great idea: Avoid the
myth of multitasking, concentrate on ONE thing at a time (pretty difficult, with multiple windows open and several sources of distraction always available).
The guys from
Freeverse found a simple-yet-clever solution called
think (oops - for Mac only). Just add a (graphical) curtain (called backdrop) to your screen - nice thing, very useable.
Here's a list of appropriate keyboard shortcuts:
Command+Option+Return will raise Think and show its dashboard
Commond+Control+Return will re-focus on the illuminated app
Command+Option+Tab will illuminate the frontmost app - sending others behind the curtain.
