Overdys simulates different reading aid modes:

- Overlay: simulates a customizable color overlay on the entire screen

- Ruler: simulates a reading ruler with a customizable color slot and masking the rest of the screen

- Line: simulates a horizontal visual guide to keep the attention on the line to read

Customizable shortcuts enable visual aid activation, as well as switching between modes
