also; From any bookmarked page, I want to be able to delete the bookmark, without having to go into bookmark manager, figure out which folder it's in and delete it.

When I've read the page, I don't need the bookmark anymore.

This is the #1 reason why I have > 60,000 bookmarks. I'd bet that 99% of them are obsolete, or I eventually read them. But it's kind of a monumental task to actually curate them.

I try to only bookmark things that are likely to remain relevant to me long term to some degree, and/or would be a pity to lose a path to for some reason.

But this is very hard to judge accurately
