Personnally I use tags for this usecase, I tag every single note in obsidian and I use a plugin called Tag Wrangler to show my tags as a tree. Tags then act like folders (for example a tag #python/pip will be under python > pip). Pros : - A note can fall under as many tags as you want - The map view is pleasing to watch because tags can be shown but folders cannot, it also helps to categorize orhpan notes visually Cons : - You have to maintain the habit to tag each notes you write Finally, Tag Wrangler allows you to rename / edit tags in bulk so that it is close to be as fluid as moving notes between folders.
