@AlexBob, I just implemented the auto-press F5 functionality:
https://github.com/Arcitectus/Sanderling/commit/dabcecbcd1e8c28ca57b58183995d0e95577ba04
This function is supported with a command-line argument, analogous to the existing ones
To use the auto-press F5 functionality, append the argument to the command line starting the Sanderling app as follows:
Sanderling.exe --bot-crash-retry-count-max=4
You can download the Sanderling app with this functionality from https://github.com/Arcitectus/Sanderling/releases/download/v2019-05-13/2019-05-13.Sanderling.exe
