Feature suggestion: editor support improvements

[fgm]

Hello,

Thanks for the plugin. Being able to use the JetBrains IDEs (GoLand for me) for TLA+ is a massive improvement over the Toolbox UI in terms of developer experience, especially for people with a non-optimal eyesight. There are a few editor improvements I noticed could make it even better, if you are interested:

• outline / folding support. For example, in PlusCal, it would be nice to have folding available on various levels, including process, labels, with, while, if / then / else, (fair) algorithm, and the complete code translation.
• Brace matching: being able to use brace matching (^M) to navigate from one extremity of something foldable (e.g. process) to the other extremity would be nice
• individual and global folding/unfolding / filtering in the output window, based on the @!@!@STARTMSG 2200:0@!@!@ / @!@!@ENDMSG 2200 @!@!@ matching, like you appear to do for the error trace already.

Also, a couple of extra features could be useful:

• the ability to render to PDF (tlatools.jar tla2tex.TLA + pdflatex)
• the ability to evaluate global constant Foo like the Toolbox: can be done like the toolbox with a temporary model generated on the fly or, possibly more simply, by temporarily adding a ASSUME PrintT(<<"$!@$!@$!@$", Foo>>) before running, grepping output for it, and stripping the wrapping around the result

Thank you for your suggestions.
They sound indeed nice, but some of them seems not straightforward to implement so let me consider how to achieve.

About brace matching:
I wondered why brace matching for PlusCal doesn't work while BraceMatcher is already registered (https://github.com/ocadaruma/tlaplus-intellij-plugin/blob/v0.9.7/src/main/resources/META-INF/plugin.xml#L123).

After investigation, I figured out that this is a bug of Intellij IDEA that prevents MatchBraceAction to work in injected code fragment
(JetBrains/intellij-community#2953)

Please take a look if interested.

Looks like your fix was accepted on (JetBrains/intellij-community#2953)
