The GUI of Proxmox looks really good, although I would be happy to be able to adjust some views, the biggest problem (maybe also "buggy", because somehow completely unusable) is the mobile view. If trying to use either with iPhone, iPad, Android or any of the desktop browsers, the views are cut, somehow unscrollable or worse scrollable, so always need a desktop system, that's sad as it could be possible, but anyhow the scripts seems to adjust the screen size also on desktop browser apps.
