I love this thing! You've done a great job on it.
Unfortunately, the program intercepts the Tab key whilever it is running (including in Desktop mode). I use the Tab key in many apps, including software development IDEs, word processing, and even web browsing.
Is it possible to limit Tab key detection to times when the live desktop is the foreground app? Alternatively, could the desktop mode key be user-selectable so it could be set to something that wouldn't interfere with other software?
Arguably the current behaviour is not a bug but a feature. However, it makes the program unusable with at least some other software, which is a shame.
