As such a heavy user of bookmarks that I pay cash money for a 3rd party bookmark manager: literally any improvements would be great. The built-in bookmark managers of browsers - especially mobile ones - are incredibly anemic.
EDIT: The bookmark manager I pay for is called Linkman - http://www.outertech.com/en/bookmark-manager. I first bought it around 10 years ago and still use an old version, so unfortunately I'm neither up-to-date with its present capabilities nor the current landscape of 3rd party bookmark managers.
I book mark often. Unless you have rigid discipline your bookmarks will end up as a huge confusing list. Current bookmark managers feel like an afterthough. <tinfoil>Google don't want you to use bookmarks. They want you to search so they can mine data and serve ads</tinfoil>.
I'd pay money for a book mark manager that could organise my list of about 2,000 bookmarks. That software could have a "bulk bookmark import" feature so that users can share some set of bookmarks. "Here is my list of best pages about $ANIME_SERIES".
A bookmark manager that looked a bit like Pinterest, and that has options to locally save some content, is something I'd pay money for.
It's hard for large browsers to improve bookmarks because people use them in such varied ways. Changing bookmarks to work more like Pinterest may work well for you, but it may completely break someone else's workflow.
One solution would be to let you install third-party bookmark managers which would replace the built-in bookmark UI. That seems even more ripe for abuse than features like custom toolbars, though, which are already heavily abused in current browsers.
Using Firefox and bookmarking heavily with giving tags to my bookmarks. I would like to have a bookmark simple search language that allows me to combine the tags and narrow down the results, for example:
give me all bookmarks that are tagged "tools" AND "unix" AND "visualization" AND (NOT HAVING "monitoring")
There is an add-on called "tagsieve" that I used heavily, it had a nice visual possibility to filter the bookmarks with a tag cloud - though it didn't have a search language. But throughout the years often it was not compatible with new Firefox version (just see that it is installable again).
