AppImages provide a nice way to users to use applications, alongside flatpack and snaps. While they are simple to use, having low-friction integration is welcome. AppImageLauncher streamlines the process for end-users by: moving them to a dedicated folder, setting the executable bit, and integrating the app into the user's DE ( using .desktop files, etc). This is done with a prompt when clicking an AppImage file for the first time. It also provides dialogs for automated cleanup/removal for AppImages.
While this kind of support for AppImages would be a nice addition to Budgie as first-party support, AppImageLauncher can provide this for Solus users without needing to make any changes to the existing environment.
