The concept of using a radial menu makes launching
application much more easier. However improvements
could be made to streamline the launch of ShortCutter
by implementing mouse click triggers
for example clicking the left and right buttons
simultaneously would show ShortCutter. The user could
also customize the default show hotkey as right click
and middle click or other combinations.
I believe with this idea in mind, it would further
improve upon user friendliness of your program and make
launching applications done with only your mouse,
leaving your other hand free for other menial tasks
such as reaching out for the cup of coffee on the table.
