I tried hyper v2 recently, took some time to fiddle with plugins and config everything to my liking. It was usable, though missing the ability to launch different shells in different tabs (I'm a windows user, so being able to have a git bash tab, a cmd tab, a powershell tab, a wsl tab, etc. is kind of a must).
This morning I was prompted to upgrade to hyper v3, I clicked yes, it refreshed. All my plugins and configs were gone. No prior warnings, no suggested upgrade path, just full wipeout. I uninstalled hyper and went back to cmder.
