keyboard indicator

[Jonathan Riddell]

Chatting with the Slimbook devs we noticed they wanted a programme
called keyboard-indicator installed.  Slimbook laptops don't have an
LED on caps lock/num lock etc like some other laptops do so there's no
visual indicator that you have caps lock turned on.
keyboard-indicator is a simple systray icon which shows up when you
have caps lock etc turned on. However it's a gtk app

Do we have anything similar in Plasma land or thoughts on how easy it
would be to implement?
