pin Quite a few, yes. I only tested this in a messy VM just now, though.

So it seems to me that version 7 is "native" while version 6 is a Linux build?
It's the libreoffice package that looks quite "retro". The libreoffice6-bin one looks like plain old gtk2 but doesn't take notice of any gtk themes. So they both look sort of... dull. 😅
NB: For what it's worth, I did enable Linux emulation in /etc/fstab(procfs, tmpfs etc.) but I admit I'm sort of new to this and still have some research to do...
