I'd +1 for having thermistor inputs (or temp sensing channels) being designated and viewable in a way that makes it easier to manage. I recently upgraded my corexy with a repaired duetwifi board, which has a problem with one thermistor channel, so I wanted to use the e1 thermistor with the e0 heater output, but couldn't get it to work.
EDIT as the board was faulty so ignor that, but being able to just display temp channel x would be handy, and decoupling the temperature channels from the heaters would alo be useful, could always have a table in config where you assign temp. channels to heaters.
