Mostly. I patched that package to support global search (show all tags across all files that roughly match this string) and I fixed a number of bugs where file paths didn't get normalized correctly. And I refactored the indexing logic (moved it to the crontab) so all libraries I use also get indexed properly.
Since I use it for Python/Django/CSS/JS work I also had to add some rules to ~/.ctags to correctly identify JS and CSS declarations.
Ah, I've been missing the functionality to auto-complete symbols from other files in the project (or libs).
Mind sharing your work?
It doesn't do auto-complete (even though it's trivial to add). For that I just use SublimeCodeIntel.
