Obsidian is a not-very-organized mess unfortunately; I still haven't figured this out but it's good enough for me to usually find things I remember. Confluence is organized as such https://docs.divio.com/documentation-system/. This works great.I always know where to put something and where to find it again later.
I also don't keep tabs open, I write things on a Todo list in Obsidian. Then at the beginning and end of the day I organize it; finishing small things like "record this", prioritizing, and moving project specific tasks to a page just for that project.
