I rely heavily on thought types and link types. The inability to at least assign existing thought and link types (if not actually create new ones) ends up defeating some of the purpose of why I use the brain in the first place as I have to remember to go back and add that information when I'm at my pc. Stress!! It makes things more complex instead of simpler.

I'd almost have to tag every Android-created thought with something to help me remember to make those updates later. If I'm adding a thought I only want to have to add it once.

Some of these basic features in the desktop version of the brain are so robust and so integral to the whole experience that it's a little crippling to be without them on the mobile platform.
