Remembering, referencing or even typing out the syntax, all the time is not great.

When within a `$$` area, and the user types `\`, start offering autocompletion/syntax, like in IDE, snippets/function name completion.

Feature suggestion 2: Understand the syntax for brackets. For example, when typing `\frac{`, it automatically changes to `\frac{}`. If there aren't 2 pairs, even empty ones, it will be a fatal error in rendering. It should instead change to `\frac{}{}`.

Sounds like a good idea for a plugin. Seems quite complicated, however
