Absoltely agree. Love the UI, add-ons(love the terminal add on). I agree go-to decalaration needs to be fixed. There are a couple of packages that try to do it, but none of them do a good job. Atom needs to fix this on priority, it's a basic feature that must work out of the box. I have got this working by manually generating ctags(installed with brew) and then using the same go to declaration option. Works like a charm like it should have :)
