 This plugin is written by me (nsf) as a result of frustration with GoSublime. I wanted something simpler and plugin has to use system version of the gocode. As you may know, GoSublime uses a fork of gocode, which is integrated into its own daemon called MarGo (as far as I know).
 
-I don't have any big plans on this plugin. The reason why I moved to sublime in the first place is, again, frustration, but with Atom (too slow). We'll see how it goes. I think I might add gofmt on save also and perhaps it's worth adding proper support for snippets, because there is no nice way to show function arguments in sublime.
+The plugin does:
+
+1. Basic gocode autocompletion. I did my best presenting the results to the user. Maybe it's possible to improve that part a bit, not quite sure yet. For functions I use "{**name**}\t{**returns**}", for everything else "{**name**}\t{**type**}". In addition to that functions are properly augmented with argument snippets.
+
+2. Gofmt on save. Here I use difflib to calculate differences, which results in line by line changes. GoSublime uses [google-diff-match-patch](https://code.google.com/archive/p/google-diff-match-patch/) library, which calculates changes on finer granularity, maybe I should switch to that lib as well.

 Oh yes, this plugin uses GoSublime syntax files for Go. Well, they use a fork of gocode, I'll use the fork of their syntax files, fair deal.
