is out now, with auto complete support. From the UI perspective, auto complete works a bit differently than what's in Sublime Text: Press Ctrl+Space (all platforms) to activate auto complete, this will insert the most likely option, and show a list of the other available completions. Press Ctrl+Space again or Ctrl+Shift+Space to cycle through the available options.
It's worth noting that apart from escape, no other keys are hijacked when the auto complete list is displayed: the arrow keys will move the cursor, and not select different options in the auto complete list. Auto complete will work with multiple selections, but only if each selection has the same text before it.
There are a few other changes too: a duplicate line command, pressing F3 to go the next find result will centre the result on screen, rather than having it near the edge of the screen (the same change will also effect bookmarks and goto symbol when they're implemented), and Ctrl+F4/Ctrl+w will now close transient views (i.e, what you get when single clicking on a file in the project).
