I've had a lovely time working with Obsidian.md. Some day I will have to do a proper write-up of how I'm using it to organize my brain.
The TL;DR version is that I had a mental log-jam in March, when the kids finished their first D&D campaign while I was also in the middle of starting some new things for the day job. I made a vault for D&D, and dumped ALL of the stuff there (removing it from the scattering of notes I had in places, and netting out all the relationships I kind of had just lying around in my head). I made another vault for the rest of what is in my brain, and that is proceeding at a slower pace.
In any event, the way things have evolved, I needed a plugin that did something a little differently for a specific kind of task that is associated with a project, so I created the Task Collector plugin.
