> Initial impressions: it's early days but this thing is just oozing for customisation. The fact it's written in JS means writing packages is pretty simple compared to Python for ST; we're going to see TONNES of addons for it. I can already think of 2-3 I'd like to build.

This isn't why it's going to be popular for plugin development though. Sublime plugins are Python, which isn't that hard to learn.

Atom's plugins are worth looking forward to if the API is more extensive than Sublime. There is too much you can't do in Sublime Text plugin authoring.
