@kirill1996 I am not sure how "AI" would help here:
Vivaldi does not have tags or categories, so that would need to be implemented first anyway
The use of folders is maybe more applicable, and you can make your own folders and sort them as needed already
It would be very unlikely that a LLM will correctly categorise a website just by the URL, and this would likely just mess up user's bookmarks
I'm not sure what you mean by "links in history". If you use the history panel you can already use "sort by page views".
In any case, bookmarks can be controlled via a browser extension, so maybe if a chatbot company makes a prototype of what this could look like, that might explain better / identify if there are features that extensions couldn't support on their own.
(aside, users complain enough as it is about the small amount of megabytes used for mail/feeds, I can't imagine people would be happy about the 10s of GBs the opera model apparently needs.)
