Hi,

What is the checkbox "Stay Resident" in the default options? What does it do exactly?

I'd like to know, also, what is "key_id" in the mpsites.json? It looks like a hash, I guess it's used to check if the master key match with the one entered for the first time, can you confirm my thought? Is there something else to know about it? I don't really feel confident having this in plain text, it could be used to bruteforce the master key.

Thank you

   Stay Resident means the program remains active after closing its window so that it can be re-opened easily using the system-wide hotkey.

   key_id is a SHA256 hash of the 64-byte master key. It's safe to disclose publicly, since 64-bytes is far too large a space to search for a SHA256 hash match.

   If you're concerned, here's what 1000 AntMiners going at it would look like (you can play with these using the timetocrack script in the repo):
