I tried Obsidian, and it is a very capable piece of software. However, I wanted it to run in a docker container. Running in a container, it uses KasmVNC. So, every doccument you wish to save in Obsidian, you first have to paste into KasmVNC’s clipboard, then paste it into the doccument. I found that quite clumsy.

If I’m doing it wrong, please share. Obsidian was my first choice.
