> I dislike mind maps because they always impose a central point/root and enforce hierarchy. That was my pain, like when I began to gather information about triangles and took "triangle" as a root point but then I need to change the root point to "flat figures" and I realize that there is no easy way to change the root point in mind-map software I have tried. This problem of mine has been solved with Zettelcasten, currently I am using Obsidian but going to switch for something FOSS.
