@lyncia Mascot programs currently include MaCoPiX (it's the one I use) and some others that apparently existed back then..

Otherwise to make it yourself
you need a UI toolkit with full permissions so that you can make borderless transparent windows and constantly monitor/be notified about the current active window, so you can move your mascot to it..

@lyncia xteddy?

@lyncia your best bet in the Wayland era would be to use a wlroots-based compositor (like Hyprland or Sway or Wayfire) and then implement a program that uses wlr-layer-shell maybe?

I wonder if anyone did that already tho?

@lyncia there used to be for X11, I'm not aware of any for Wayland.

@lyncia oh i definitely saw something recently for Wayland that does this, but i can't remember where. I'll link you if i can find it!
