This is a work in progress. (Sorry about the previous formatting. Posted it then got distracted.)

I’ve tried to keep fairly faithful to the VIS tags while also satisfying my need to organize. Suggestions are welcome.

() - top
[] - most commonly used <-- most items will use this.
{} - force down
|| - Absolute bottom

Tag is first, then the icon used and then any notes.
