I loved how slide for reddit solved that. You could set it to mark posts as read on scrolling them of screen and you’d have a floating button to hide read posts. So you could easily check for new comments or find new posts.

I use Linkding. Imported all bookmarks from browser and added tags. Helps me find stuff later. Search is also good. My bookmark bar in the browser is now only for quickly accessing the stuff I need daily.

+1 for mxroute. Happy customer since last black Friday. No fuss and just works (after reading the how-to). Also spam detection is good.
