There are a few sites I visit very frequently and I find myself always opening a new tab. I'm used to an IDE where if you click on a file on the left it takes you to a new editor, and if the editor already exists it just takes you to that. So I thought I'd make something similar for a web browser. I admit I used AI. One hour well spent because now I don't have the too-many-tabs problem anymore.
Maybe this solution already exists? I couldn't find it.
Enjoy! And if you decide to tweak it, please submit your work back in a PR! Or of course you're welcome to fork it. Please share your improvements!
