Has there been any discussion of adding the ability to monitor and show how full your kegs/batches are?
I would be interested in this too.
You might want to look at Raspberry Pints. You can get flow measuring devices and put them inline to show how much you have drank. Taplist.io would probably just need to have a button(s) to say that you just poured a pint and then do the math.
It one of the top requested features, support for which is currently in private beta & coming soon. See more here:
