Enjoying Vivaldi

So far I’m enjoying Vivladi. Thanks to Jack, I realized I was stuck in a “Vertical Left” present, which - as he says - makes the address bar too short and weird and also hides some of the buttons. At least for now, as I’m learning it, I want to see everything. The Tab Stacks are better than I realized. I use the accordion mode to get stuff out of the way when I’m just browsing, but when I’m doing one of the usual activities (like blogging from Linux, as I do now), I work within that stack. I really like the fact that my blog’s stack has my blog’s colors. It makes it stand out from the rest and invites me to write a post. Also, split-screen view is especially useful when blogging: I write on the left, while I have references and other tools I use (like Inkwell, or a site I’m quoting from) to the right. It may seem small, but the fact that I don’t need to switch tabs makes blogging much easier; on Safari, I drag a tab out of the pack to create its own window, but it feels forced, it slower, and it doesn’t dock next to it as nicely. There are probably a million other features I don’t know about. In fact, let me ask you, if you use Vivaldi (especially on Linux): what have you discovered? What’s one thing or maybe two you use often and consider a must-have?
