Works well for me without any other input other than downloading and turning it on in my toolbar. I really like the options to change colors. I wish it would not repeat the keystroke if I hold the key, as I often do if I'm using shortcuts for tools. I also wish the keystroke visibility was able to be turned off, or had the option to make it smaller.

It does not work!

Doesn't even work ugh

This is a great little extension that got dinged down to 4 stars because it really needs more documentation. Over in Support, I put in a few tips about turning it on, checking if it's active, etc. The "Options" option is grayed out and unavailable in both this and CL. The Crafty family of extensions is pretty cool, and it would just take a second to put some basic info up.
