I think this is great advice. Two of the biggest annoyances I had with Sublime Text were the autocomplete suggestions and the bracket/parenthesis matching (or lack thereof).

I still think the default behavior (as of Sublime Text 3.0) is pretty broken with both. For autocomplete suggestions I found this to fix the problem:

For bracket/parenthesis matching it was annoying me so often that I ended up fixing it myself by writing a plugin:

I think this advice rings true for more than just editors. Third party libraries, browsers, frameworks, etc, all have their limitations/weaknesses and fixing things that annoy you is always better than living with the problems.
