Draw.io

I was looking for a tool to help with planning my game, cause simple notes apps didnt work for me.

I found milonotes which was almost perfcet except for the subscription based model and not being FOSS.

Then I stumbled upon Drawio`` Now I can use most of the screen space and separate my ideas in a way i find logical.

10/10 I suggest you try it if you want a whiteboard type notes app.
