Things I'd add to browser bookmark managers someday:

- Support for (persisting) bookmarks tags. From the post re: the re-launch of del.icio.us: https://news.ycombinator.com/item?id=23985623

> "Allow reading and writing bookmark tags" https://bugzilla.mozilla.org/show_bug.cgi?id=1225916

> Notes re: how this could be standardized with JSON-LD: https://bugzilla.mozilla.org/show_bug.cgi?id=1225916#c116

> The existing Web Experiment for persisting bookmark tags: https://github.com/azappella/webextension-experiment-tags/bl...

- Standard search features like operators: ((term) AND (term2)) OR term3

- Regex search

- (Chrome) show the createdDate and allow (non-destructive) sort by date

- Native sync API for syncing to zero or more bookmarks / personal data storage providers

- Support for integration with extensions that support actual resource metadata like Zotero

- Linked Data support: extract and store bibliographic metadata like Zotero and OpenLink Structured Data Sniffer

What are the current limitations of the WebExtensions Bookmarks API (now supported by Firefox, Chrome, Edge, and hopefully eventually Safari)?: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/Web...
