So again, i made it for myself. I am seeing if there would be any value if me making it configurable and sharing with others. Software would be free, and open source. I would accept donations though.
Sounds like a useful enhancement above basic sh/BAT files. Put it up at Github.
It also makes sure i finish each pplns cycle before switching as the hub itself is managing my coin switching.
This is likely to be the most useful feature, because MPH already takes care of it for you on 17xxx and 12xxxx. So if you can use that on the 20xxxx ports or other pools, it's very useful.
