Unfortunately, I doubt you're going to get these same level of autocompletion as IntelliJ et al simply due to the amount of indexing that IDE does.

It's a trade-off, there are times in code, I just don't get autocomplete, especially from other file references... or it starts a few moments after I've opened the file... On the flip side, code never seems to just wig out and freeze for several seconds at a time (after initial open) like most IDEs tend to.

I'll take having to remember what I'm trying to type, look it up etc, and have autocomplete mostly work, vs. my editor wigging out in a large project for a really small change.

Also, absolutely love the integrated terminal and the git integration, though better merge/rebase would be nice.

Yes, definitely have faced that problem with IntelliJ. It eats up memory and consumption grows while the IDE stays open, which it always does for me. Better autocomplete would be the killer feature that would win me over, so fingers crossed it gets better!

Have you tried ternjs (Sublime Package: https://github.com/ternjs/tern_for_sublime)? I use the config file from https://github.com/tststs/atom-ternjs/blob/master/README.md#... as a basis, works quite well.

I'll give it a shot. Thanks for the recommendation!
