Comment 8 for bug 773078

Without this indicator, StickyKeys is basically unusable. Obviously you can use it, but if you lose track of which keys are locked/latched, it's really tricky to find out what's going on. I have in the past been forced to reboot just to clear a state of confusion. I would rate this bug as at least Important, possibly Critical, especially considering Canonical's statements regarding making the next LTS as accessible as possible.

Windows handles it very poorly, with a teeny tiny systray indicator for all four meta keys.

MacOS, last I used it, handled it very well with a relatively large overlay appearing graphic screen-left for each latch/lock key composited on top of the desktop and open apps.

What would also be very useful in these days of Unity and Gnome Shell using Super/Windows as a Start-button-a-like would be the ability to exclude the Super/Windows key from being sticky. It really breaks the UX for both Unity and Shell to have that key locking (turn on StickyKeys and see what I mean).

Hope this helps. If there is anything I can do to be more useful, please let me know. I'm not much of a programmer, but I do have some UI design experience.
