Hi, I just wanted to state, that I also would be verry interrested in getting this optimized.
I am using ubuntu gnome with the system setting "dark" and the "arc dark" theme. There are just a view apps I am using regularely which do not seem to fit into the "dark theme" - unfortunately enpass is one.
Btw.: I am using enpass now with my nextCloud to keep my laptop / workstation / mobile phone in sync. It is working really, really well! Thank you!!!
