More than 2 master zones

I’m using OpenSprinkler for an indoor cannabis grow, and we love it. Thank you for creating this great product. There are just a couple things I wish we could change. I’m not sure if this might be possible to implement in a future update, or if I could pay someone to modify the firmware for me?

The first item is simple, I would like to have 4 master zones instead of the current 2.

The other thing is I would like to be able to manually start a program while another program is currently running. We can manually start multiple zones individually and they queue up or run simultaneously depending on their sequential group (this works great). But if we manually start a program, and then try to manually start another program (consisting of zones with a different sequential group from the first program), it won’t go. This seems to me like it would be an easy fix?

Thanks,
Arbor
