@joshsusser both, actually
We use Notion at $job and I’m trying to use it to handle a “work plan” format I use to break high-level goals into smaller, individually accomplishable things; it’s really more of a graph but I can make it work with outlines
On the flip side, I’ve got a lot of personal projects that have similar concerns — for example, DIY electronics, I want to track each project separately but also “gather” things marked as “blocked:parts” for a mouser order
