Do this support C++11? there's already some days I'm looking a new IDE/text editor with real C++11 support to I switch to. Also, I can change the theme too, right? this black isn't very good to my eyes.
Sublime is an awesome text editor. It is not an IDE. Most notably lacking is any project level code intelligence. You can't, for instance, click a method name and go to its definition and this is not easily solved by a plugin. You also can't get intellisense for custom functions. I love Sublime as an editor, but the lack of those two things make it a poor IDE for any project of any complexity.
Sublime is a text editor, so it doesn't offer debug/refactoring or other IDE features for languages out of the box. But you should find plenty of plugins that can help with different things, and it will syntax highlight just fine out of the box. What type of support are you looking for?
