I just installed it with Flatpak on my Fedora Macbook. I need to play around with it, but my 5-minute impression is so far pretty good. I don’t really get the point of the sidebar since I use the web search plugin for KRunner on my main desktop. I guess it’s good for people who don’t have KRunner since they could add a bunch of commonly used websites like Wikipedia and Google Translate.
Edit:
Split tab is very interesting. Not good for the laptop because the screen size is too small but it can have good use for my desktop.
I still have to use tree style tabs to be able to organize my tabs in a tree structure, but I’m (mostly) able to hide the default tabs unlike Firefox where the horizontal tabs sitting awkwardly on the top alongside the tree style tabs.
I’ve always hated horizontal tabs. It’s one of the reasons why I started using Firefox way back in like 2006 because there’s a popular extension that gave you vertical tabs. Horizontal tabs suck once you have 10+ tabs open and I have 70+ tabs lol
