That's not what I need. I'm used to having a list of all functions / declaration in the current file, always visible, and I just can't live without it.

For functions there's cmd-R. Declarations I'm not sure though, I think this would need a language specific plugin.

One thing though, cmd-R doesn't work very well with closures, it gets a bit messy - the good thing is that you can just start typing words you know from the function's name and it will list anything relevant.

Could you provide a link to a screenshot/example of what you're talking about. I understand the gist of what you're describing; I believe I've been looking for the same thing.

The Vim plugin Tagbar matches ozh’s description. The Tagbar site has some screenshots: http://majutsushi.github.io/tagbar/.

An equivalent plugin would be harder to implement in Sublime Text, because Vim has identification of “tags” (function/class names) built-in, and the Tagbar plugin just displays them. I don’t think Sublime Text’s syntax highlighting rules do any equivalent thing. So a Tagbar-like plugin might need to parse the code itself to identify tags.

I'm used to something like this: http://i.imgur.com/gAQhd.png and I have a very hard time not using it (function list on the right). When hovering a function you also get a hint on parameters.

Can be moved to the right:
