Hey! I thought that it would be cool to create something that would help with my note taking daily routine using Xournal++ in pair with Obsidian. There is a plugin, but due to some features lacking, and my will to code something after switching to linux.
Here you go with my fresh release of xjobsidian, a package for terminal that, hopefully, will help you with your workflow.
It simultaneously creates .xopp note, pdf with the contents of the note with update on change and markdown with embedded pdf, and opens those in Xournal++ and Obsidian respectively.
The project is in early stage, so propose any changes!
