Thank you for building this awesome plugin. This plugin works pretty well and helps me to use latex.

I'm trying to build my own snippets, and the idea of $symbol variable can make snippet more elegant. Is it possible to define more variable and edit exist $symbol?

here's some example to show the importance of variable editing:

• ll is included in $symbol, which cause default snippet lll failed
• symbols can be set to different category, times need auto spacing, but leq sometimes need auto subscript

Good idea, I can add this to a future release.
