Sublime Text user experience

[AmjadBHD]

Just to add a note there's an 
[extension](https://github.com/BenjaminSchaaf/sbnf) (rust crate) made by one of 
Sublime text's core devs that creates an ST4077+ compatible sublime syntax file 
from a BNF like grammar. That + 
<https://nim-lang.org/docs/manual.html#syntax-grammar> should make it easier to 
create a decent sublime syntax.
