I try SublimeText few days and I start to love it but… it miss one feature what there is in Netbeans (I can’t live without it). When I need CodeIgniter auto completion, I put just several lice code in my project like this:

After it Netbeans automagically scan project (and codeigniter functions) and give me nice CI autocompletion.
Maybe somebody can do any plugin to do it this way? It will help many people to code (not only CodeIgniter user!)
