Yes, a little and it's pretty good, only tried it for editing some javascript code though, haven't used the 'build desktop app' stuff yet though, looks interesting!

Whoops, I tell a lie!
I have only used Atom which apparently is built on top of Electron and is why I can see the same Icon on my taskbar shortcut (the tooltip also says it's Electron??). It probably explains why I haven't used the desktop stuff either
