What does 'automatically explore the glyph mines' actually do?

Hi all,

It seems pretty self explanatory, but I would like to know for sure before I spend money on it (I know you get a 3 day free trail, but I always forget to cancel those subscriptions so I will pay for at least a month ^^). I can’t seem to find an explanation anywhere what it actually does. How many gliphs will it mine per day and will it mine from all the mines or just the highest one that is unlocked at that moment?

Thanks in advance!

It mines from the highest available unlocked mine, then mines lower ones until a higher one opens up again. It continues automatically until you tell it to stop manually, you run out of energy, or your glyph bag gets full. It’s quite handy.
