This is incredible! The ability to grab the URL with yy alone is worth it! So easy to do yy Cmd-Tab Cmd-V and send someone a URL. The other cool thing is gu to "go up" a level - when a URL isn't working because of a site reorg this is helpful. And W to pop the tab to a new window. If you just do those 3 things you will love this even if you haven't learned vim. If you have... then I don't need to tell you any more...

like it!

This is an amazing extension, even if you don't use vim for everything:
If you're at least somehow familiar with vim keybindings you'll quickly adapt to vimium, which main point for me is using less mouse and more hotkeys.

It has two main issues for me:
It doesn't work everywhere (for example in Jira i can't navigate the board with vim keybinds)
It doesn't support editing with vim keybinds which is understandable and idk which behavior would be more usable, but still can't help but insert some j's and k's into posts
