i just bought my 1st dna today. (Therion 166) i was hoping to change the way the device locks to pressing the + and - buttons at the same time. i really hate the 5x to lock. i also never use temp control so other than visual stuff i guess theres not much i want to change in escribe? should i load a profile for my HG2s? Any other cool features i should learn about? possible firmware updates?
