After using Joplin for a few more weeks, I've realize that this issue isn't simply "how to show stuff in the app". It goes deeper into "how do I structure the information logically across notebooks, notes, headings, subheadings". If you don't make the right decision at the start, you'll find yourself spending time restructuring your notes, or spending too much time trying to find information.
Your notebook / sub-notebook structure is of fundamental importance to how you can use your notes. For example, if you want to use the Quick Links plugin, then you must remember that it cannot link to headings within notebooks. If this is important for you, then you pretty much have to put your entire document structure into the notebook tree and keep your notes within each hierarchy ultra simple. But that has trade-offs too. If you have several unrelated notebooks, Quick Links will be searching across all of them.
I'm in a situation where, after months, I still don't feel comfortable with Joplin. I constantly get yanked out of the subject I'm studying because I 'mentally stub my toe' on the structure of my notes. For example
1 . I want to refer to information in another note, but the list of notes in the notebook is long, and doesn't seem to be ordered, so I scroll up and down trying to find it.
2. I have to navigate into another note to get the heading anchor so that I can go back and create a link
3. TOC!!! Why is there no out-of-the-box support for TOCs within notes, or across notes in a sub-notebook structure?
If you don't get your notebook structure "just right" you will find yourself slowed down when taking notes or finding existing notes. Countless times I've just stopped studying and started looking online for Joplin plugins to make note-taking and revision easier. When that fails, I start restructuring my notes into more sub-notebooks (or sometimes, the reverse). In other words, I'm not taking notes or revising any more. I'm bike shedding. (Case in point: right now I'm supposed to be taking notes but I'm on the Joplin forum again looking for pointers)
If I could easily add multiple 'major' notebooks that each sync to a different back-end, or even to a different directory within Dropbox, then I could at least "partition my searches" across different major subjects and make better use of the notebook hierarchy.
I'm struggling here. Has anybody ever recorded a YouTube video that shows how they structure a large subject and handle the various things I'm describing?
If I can't work out a comfortable note-taking / revision pattern in the next day I think I'm gonna give up on Joplin (again, permanently) and go back to managing a directory structure full of .md files, and just use Syncthing to keep them in sync across my devices
