Well I hate to also semi-dismiss your message, BUT when certain add-ons are essential to using a tool like Atom it makes it slow and bloated.
For example I use vim, and when I tried Atom I threw on two Haskel add-ons and my system was unusable. Then I removed the add ons and my 7 year old desktop on OpenSUSE just lagged away. I than went to my other old desktop all in one and that lagged away just at typing (This was a month ago) and adding anything to Atom slowed down so much that typing was lagging let alone any feature.
