I use obsidian as general note taking (I use a daily zettelkasten note to dump whatever stuff inside in situations where thinking and deciding about making a new file, with which name and where would disrupt the flow or would be too slow. I may put the content somewhere else after). I also use it for more organised stuff, like I have a folder in my obsidian vault about job/conference etc applications, another folder about work presentations etc.

I use zettlr on more project related documents, that typically reside in a `doc` folder in the respective project directories rather than in my obsidian vault. This is much faster as usually I am already working in that directory, and opening things in an obsidian vault is too distracting then. I would say that in general compartmentalising between work within a project and the general context/structure of my notes helps me a lot with not interrupting my flow states, even if this just began because of different software conveniences.

Sometimes I also work on md files in my obsidian vault using zettlr because I like a bit more how it handles pasting images from clipboard memory (gives you the option to resize the image on the fly, not sure if this is possible somehow in obsidian).
