1. Regarding templates: I'm not sure the following method is helpful, but I keep LaTeX templates in ~/Library/Application Support/LaTeX/Templates
and in TextMate simply save a new document as file.tex, type temp + tab to choose one of my templates.
Re #1: This was what I did for years. The temp + tab function no longer works. I get the message ``Failure running ``Latex Template'' LaTeX Template:11:in `to_plist': no implicit conversion of Array into String (TypeError) from LaTeX Template:11:in `<main>' ''
Previous text mate list entries indicate that the template function is discontinued and that snippets should be used instead.
Re #2: Thank you! This is exactly what I want.
It still seems that I cannot delete old snippets or move them to other areas of the bundle?
