re: thread title - I've got your request, I'm just trying to sort out a new public preview build for later this week at which point I'll also action new beta requests.
For what's in the screenshot, I wasn't even aware of those options in Explorer. I'm not able to replicate the issue at the moment (my machine keeps trying to use an old beta build with that action that I need to resolve first) but shell / explorer integration isn't fully implemented at the moment so I'll log this issue for when that work is going to be done. This is why the preview build (and beta builds) are setup to work as effectively portable installs with the ability to manually associate things via the OS methods if needed.
