Can't seem to select all my mail to archive though. I have a bunch of unread mail and I would want to batch read them all.
Also another thing I'm used to in that kind of app, is scroll further than the top limit to update the list.
We've actually considered adding this and just making it a no-op-- a placebo feature to help users transition.
Once Electron got it's footing, we migrated there. It's also easier for us to contribute upstream patches for things like touch events. (We launched swipe-to-archive a couple weeks ago.)
Atom is lagging behind Electron. It's still running on Electron v0.34.5 which was shipped in November of last year. They're trying to keep up, but the community of folks around Electron is growing fast.
If you're based in SF and interested in this, you should definitely check out the Bay Area Electron User Group: http://www.meetup.com/Bay-Area-Electron-User-Group/
