Colorized sticky-key status message?

[jubilatious1]

Feature Request

I love how Karabiner and Seil help make the keyboard more 'modal', but still looking for visual aids when a Modifier key has been toggled. Seil appears best suited to changing Modifier keys like CapsLock, Control, Command, Option, and Escape keys on the Mac. Karabiner--which loads later--appears best for all other keys.

To help visualize toggled or sticky keys, I'm wondering if Tekezo would please consider adding a colorized "Status Message" for each of the five Modifier keys mentioned above? For example, maybe when the Command or Control key is toggled ON (e.g. entering "Normal" Vim-mode), the Status message could change to a particular color? To be cancelled when Normal mode is toggled off? Or if the Option key is made sticky, a second different Status color shows up until the Option key gets 'unstuck'? Or when the CapsLock is toggled ON, the Status message can be yet another (third) color?

To be most useful, I envision a color picker that locks-out colors as you assign them (e.g. 8 colors to start, assign one, leaves 7 left unassigned).

While most of the code for toggling individual Modifier keys or making them 'sticky' is in Karabiner, colorization may be best implemented in Seil, because it appears to interact more directly with the "Sticky keys" function in Universal Access.

Thank you!
