this is a simple (I think) feature to implement, just to prepare u in advance XD
Our community have developed many packages and many of them are snippets, completions and syntax. Now if I want to create a new sublime-completions file for ruby for example, the only way to have consistency through sublime is to delete the one provided and replace it with mine.
The same if I want modify a provided snippets.
As you can see this is lil troublesome because after a st update this would be overwritten.
I think that if u can extend the already present behaviour of sublime-settings and keybindings to completions, snippets and syntax.
So, if i have PHP.sublime-completions in my User folder or subfolders, this will be used instead the default one..
Looking forward your answer^
ty in advance
