Why are bookmarks done the way they are currently done at all? A bookmark is generally not highly private. It would be reasonable to sync it as one syncs their notes. It is the kind of thing one may wish to annotate in various ways. Instead of bookmarks what I really want is markdowns files that describe my relationship with that site. I want a split screen text editor on my phone that edits the notes field in that file. I want the option to save an offline copy and fulltext search it all. If not, the text file could default to an algorithmic summary. And most importantly, this should be in a folder of my choosing that SyncThing can access. I've been thinking about making an external bookmark manager that uses Android's share feature.
