Screencast Keys Addon
====================
Updated some parts and added some new options:
- Individual color (and alpha support) for text/icon and background box
- Shadows on text for better readability
- Display Last Operator option when box is active
- Background Box is now always drawn (less noise)
- Option to hide the box when no key is pressed and change its width
- Text is drawn on top of the box (used to be below)
- Reshuffled the UI a bit
This is my first commit on this addon, so any feedback is very welcome.
A lot more work is needed in this area we know, but I think in the meantime the changes so far make this addon much more flexible.
