@NaraMoore that might be the difference, I can't work longtime on a PC screen i get distracted and try to so everything else, in theory I am capable of writing ten finger system and should be faster but my focus doesn't exist at all. I can work with PCs if I'm in a office space with others and need to focus, but alone at home no chance.
On the phone it's different because running things next to each other gets annoying and confusing for me, so I tend to be way more focused. And the smaller screen helps me to not loose sight of what I'm doing.
I don't know why it is like this but it's how my brain handles things and the dark mode is also a very important thing for me.
I haven't heard of Obsidian. I will look into that for sure. :)
