Some nice tips. ST was great for me for Python work, but became borderline unusable for me because of one weird thing. In HTML mode it autocompletes snippets based on the empty string.

So typing ">" + Enter or even " " + Enter inserts the <a href=""></a> snippet. So I literally can't insert a newline at the end of any content without hitting escape.

Doesn't seem to happen in other languages. But I couldn't find how or why or how to prevent it. So I gave up. In a related note, I found documentation a bit limited.
