Agreed on the slack app... but I've been using VS Code very happily, especially since the integrated terminal was added, which is a feature I've wanted in my editor for a very long time... The terminal was pretty sluggish on some things at first, but works well... still not much of a fan of hyperterm, which shares the same terminal integration modules.

Most of the electron apps I've used I don't use much... except vs code, and for what interactions I have they aren't bad. However, most of my time is in one of several browser tabs, vs code, and a terminal window. I keep Goofy (fb mobile as electron app), and Spotify (electron iirc) open... that's about it.
