About Gromit MPX
Gromit-MPX is an on-screen annotation tool for Unix desktops. It lets you draw over running applications to highlight buttons or areas, and its stated main use is presentations. It runs under X11 and, through XWayland, in Wayland sessions. It is controlled mainly by hotkeys rather than an on-screen panel, so it does not clutter the desktop.
Pricing is not clearly stated.
Key features
- Toggle painting, clear the screen and toggle visibility with F9-based hotkeys
- Undo the last stroke with F8 and redo with SHIFT-F8
- Change key bindings and drawing tool configuration
