Might be the wrong place to ask, but: does Craft not have content search? I tried playing around with it the other day and couldn’t figure out how to get beyond searching filenames.
My workflow: everything’s in Obsidian, synced with NotePlan 3, and indexed in DEVONthink. I use Obsidian’s embedded searches (for which I recently released a plugin) to keep track of projects and tasks. I use daily notes lightly to keep track of what I’m working on and thinking about. NotePlan serves as a good mobile option to be able to review and edit work when AFK. DEVONthink is my full-indexed-search repository of all the above.
