Vivaldi’s theming feels… broken for me, so I can’t really see myself switching to it. I should mention, however, that Vivaldi is my only real option if something happens to Floorp. What can I say, I like my workspaces on desktop, bottom tab bar on mobile, and good sync across devices.
Edit: Full list of reasons:
No way to have bookmarks only show on a new tab
Inconsistent tab bar view (super compact and good-looking when window is maximised, but has pointless, inconsistent and weird gaps across parts of the top and bottom of tab bar otherwise)
No way to completely disable panel and all its features
Optional: No way (that I could find) to disable/hide speed dial Fix: switch back to using Tabliss
No way (that I could find) to fully disable/remove the Vivaldi button
Vivaldi settings sync saves and syncs only so much, so things like custom keybinds within Vivaldi (like switching from Ctrl to Alt for the modifier for tab switching) won’t be saved
