Thanks for the heads up - I just checked out gulp-autoprefixer and it looks like a cool package - might install that one tonight.
This is the sort of thing I am talking about - there must be a myriad of gulp packages out there that will be useful for Angular/Ionic projects.
In the same vein, I have been looking for Sublime Text extensions to help as well - found some good packages for prettying up code display and formatting etc. Must be some good Angular based ones out there that I have missed.
