Looks cool, but as I have been on this knowledge management / productivity journey like everybody. Here are my findings: If you are reasonably comfortable with computers / Unix. - You need to first rely on a directory structures, filenames, plaintext, lists and maybe markdown. Stick with a "File over app", Unix approach. - Try to sort things with universal concepts: locations, things, people, events, metrics, howtos.…
This is exactly the conclusion I came to. I still use Obsidian for a lot of things, but I've developed my own task management software that uses plain text files and fzf for everything: https://codeberg.org/ngp/tsk It has worked great for me! That being said, sync and mobile usage is still a bit of a sore spot with it. It works beautifully with Termux, but I wish there was some way to slap a basic UI on top of a CLI…
I have only relied on fzf so far but have played with the various components of the Termux:API [0] for basic UIs, and it works well.
There is also Termux:GUI [1] with Bash bindings which allows to build more advanced UIs.
