It works, BUT .... :/
Limited features: Basically only supports 9 “neon” coloured pencils and clunky “config” of current RGB values.
Clunky interface:
* Popup menu (top right) to: reset, save, “config”, show “palette”. Palette of 9 colours and “eraser” auto hides; so it’s a minimum of 3 taps to change colour.
* “Config” to set RGB has no preview.
* Given the “eraser” bug, the lack of ‘step undo’, really bites!
Silly bugs:
1) “Eraser” does so by drawing in white (ok, this is normal); BUT the background is black and cannot be changed (/facepalm)!
2) Opacity option in “config” does nothing. Always resets to max.
