I've been trying out Ptyxis for a few weeks now and it's quite nice to use with Distrobox or other containers. It's easy to set up profiles with particular docker containers and it automatically picks up distrobox containers.

It also has the "top bar color changes as a state indicator feature". eg: when I run a "zypper ref" the top bar goes red. The multi tab overview can be useful too, and it has a lot of color themes OOTB. These are nice touches.

Haven't used it myself, but from what I know it should "work better" with container technologies (in the sense of integate them nicer I assume)
