It couldn't expand a simple phrase correctly. But the idea is good.

I don't like that this injects jQuery into my pages. This isn't unsafe, but it causes undesired console activity when I'm working on my own software. The program sometimes fails to work and sometimes it fails to delete the trigger text.

This is a sorely needed add-on. The first time I installed it, every short form produced multiple expansions. It is hard to know why. I am turning this off for now.
