Use case or problem
Hierarchical folders are limited compared to tags, links, and MOCs. I want to have my notes sync to different devices more granularly and tags is the only way to do that.
Allow Selective Syncing feature to select tags as well as folders.
I realize this is well over one year old, but I too would love the ability to sync by tag (with an option to include all linked files to that tagged file), especially when it comes to syncing with my Android phone. I don’t want to mess around with my folder structure by creating a “phone” folder and only sync that (which is a workaround). I would much prefer to add the tag ‘phone’ to those items I always want and need no matter where I am.
