Hey, I used to have that same itch too! Curabase looks almost identical to the app I was building as a side project back in 2017. Column-based bookmarks, easy to categorize and reorganize, though I was using Material UI back then and was consumer focused.
Never launched... it became another unfinished project. I eventually realized that I don't really need to store that many bookmarks.
Lol -- I agree it is not an original idea. This is a completely selfish endeavor. I build it for myself and pretty much no one else. I do have some users right now but not enough to consider it a business.
