The new UI has a little more space between names than the old UI, which means you see fewer names if you keep the window the same size.
An example: two screenshots from a while ago, proton UI vs my current UI.
In the picture you can see that my current UI shows 20 names in local, while the proton UI can only fit 17 due to unnecessaey padding.
A compact mode could fix that, so I’m glad this is coming!
