Is using files from outside of Debian somehow avoidable? Can we pretty please only use stuff which already comes from packages.debian.org?
(Background: security, difficulty to make this work in build scripts on all platforms in all network configurations, signature verification, licensing, theoretically potentially malicious icons specifically crafted only for Whonix, Whonix ™ Default Application Policy )
Here is the list of all “icon-theme” packages in Debian: https://packages.debian.org/search?keywords=icon-theme
Personally, I don’t like most of them.
If I had to choose, I would just use the default gnome theme (already installed) or Adwaita. I just dislike the current default one - Gnome Brave - which looks childish to me.
Thank you @Patrick et al. for implementing Arc theme and Adwaita icons into the latest Whonix 15 OVA. The Buster Adwaita stock icons are way better than Stretch (e.g. folder icon in Thunar), I’m so happy, and I now consider things fully fixed in this department!
Suggestion: place the panel on top (ALL flavors)
Reasoning: at least with virt-manager, you usually don’t put the VMs in full-screen in order to easily switch between different VMs and/or Host programs.
With the current settings you end up with something like this:
i.e. you never see the panel (hidden below) and you have to enable full-screen again to do anything useful inside the VM.
With the panel placed on top, you can still access it and manage your opened applications in the VM without having the need to enable full-screen, while still keeping quick access to your Host applications:
