Missing tray icon
The Input Remapper program doesn't display a tray icon for the user to close the program. Furthermore, the tray icon could have other options in a pop-up menu. Without the tray icon, the program runs in the background and the user can't close it. We can't understand why this basic feature hasn't been implemented yet.
I get what OP is saying, but I thought it was never there. I"ve run Ubuntu 22.04 and 24.04, and Linux Mint 23.(current), none of which have ever displayed a tray icon. I've never seen that purple arrow/swirl thing before this post just now. If that is the icon you are right-clicking to show that there is a context menu from the tray icon, then your screenshot looks to be clicking the wrong program as the contents of the context menu has nothing to do with Input-Remapper. Maybe you can shed some light on what the tray icon looks like for us?
@TherinS you are right, sorry I completely made a mistake and commented on a issue of the wrong repo.
I see you deleted the erroneous post, @Rochacbruno. Thanks for correcting that. I still hope for a tray icon....
