### What should this feature add?

I've noticed an increase in crashes with my current install of invoke, I'm not sure if it's just my install or what, but it's not unreasonable to accept that there will always be the risk of crashes. However with the addition of the new launcher, I'm wondering if it's possible to have the launcher automatically restart the server in the event of a crash.

In all cases, when the server itself crashes, the launcher still remains running. It seems possible it could act as a harness to restart the server if it detects that it is no longer running. The launcher also displays "exited" when the server has crashed, so it seemingly already has knowledge of whether the server is running or not.

### Alternatives

Restarting everytime manually on crash. Works, and isn't the worst thing ever since invoke starts pretty quickly, but automatic restarts would be convenient.
