AppImage of htop.
WHY? Well btop releases binaries and htop doesn't, the appimage is just a different method of having released binaries, plus it ships with an icon and .desktop file as a single file.
It is possible that this appimage may fail to work with appimagelauncher, I recommend this alternative instead: https://github.com/ivan-hc/AM
This appimage works without fuse2
as it can use fuse3
instead.
