DORKYPANTS  Causes sleeping iBook G3 to keep waking up. Quitting Focus Layer when sleeping cures the problem.

GOSTCODER  This software is at a good start.

A feature to overlay the current desktop picture instead of a solid color would rock, it would in effect make all background windows appear to be semi transparent.

Using a menu extra was a nice innovation, how about dropping the dock icon entirely and letting us toggle/change prefs via the menu extra?

Keep up the good work.

STEVEN CHAN  Excellent software... it allows me to concentrate on one window at a time on my already-cluttered Mac desktop. Great for single-track minds like myself and artists and web developers who wish to concentrate on one piece of work at a time. Has some tiny quibbles, but overall fantastic features and outstanding value for the price.
