I noticed that too, but for some reason I can't seem to figure out how exactly it works. It's not just like in ST, as my buffers get lost. After a while I just gave up because I don't actually need to switch from ST...
There's a confusing bug related to this feature. Currently, Atom only automatically re-opens unsaved buffers in "project" windows (those associated with a particular directory). See https://github.com/atom/atom/issues/10474 for details. It's a real bummer and I hope it gets fixed soon.
I see a lot of skepticism in the comments..
is a 30 or even 20 hour week (for commensurate pay) even possible? I have lived fine on very little money before and I value my time much more, but it seems like my only option for not slaving away is working for minimum wage.
This is one of my most preferred potential arrangements...but I think the problem is that it actually benefits the worker more than the company - why hire the extra two when you can leave them unemployed and hang the threat of unemployment over your eight?
