Jon-Kyle Mohr (@jondashkyle) just released the beta for Cycle Marks, "simple bookmarks with rhythm." As he says, "With CycleMarks, you set the drip-rate for content you want to check in on.” Been using for a few months & highly recommend: cyclemarks.com

And as a dedicated Obsidian user I appreciate how you keep conversation going about that tool!
