CapsLockViewer
A tiny Caps Lock indicator that stays out of your way.
A Caps Lock indicator that sits quietly in your Windows tray: a cyan A when caps is on, a white outline when it is off, using about 10 MB of RAM. I built it because every other Caps Lock app was weirdly heavy. TrayStatus uses around 197 MB to show one keyboard bit; this does the same in about ten.

About 10 MB of RAM
Twenty times leaner than TrayStatus, which uses around 197 MB to show one keyboard bit.
Lives in the tray
A cyan A when caps is on, a white outline when off. No window, no clutter.
Polled, not hooked
It reads the key state on a 150 ms timer. No keyboard hook, nothing to slow your typing.
One source file
MIT licensed and a single C# file you can read in five minutes. Open an issue if you want to tweak it.
