In my previous editor (EditPlus) I could switch between the latest 2 files with F12, which came in very handy. I know you can switch with ctrl+tab, but then you have to remember if you need to go forward or backwards. As far as I can see F12 is not used yet.

Keep up the good work!

1. nested symbols: for example: '@SomeClass some_method -6' -- jump to to -6 line above class method
2. search symbols in many files: 'file_name@SomeClass' show all files matched file_name and contained SomeClass

In some code editors it is possible to have multiple spell check dictionaries activated at the same time. It would be a very comfortable feature in ST too, for example when working  with multilanguage text files.

I'm talking about this menu:

It would be great if the R lexer could support folding multi-line comments in R.  This is particularly useful with function headers.  Ideally, when the comments are folded only the top-most line shows (i.e. the name of the function).  Here's an example of a function header using Roxygen-style documentation. 

#' Test Function

#' My test function description

#' @param firstParam  first parameter description
