imo. you can put or rearrange for better UI, eg: put setting (frame) on single button, when clicked, a setting window will pop out, the same to connection (disconnect,com1,9600), can put measure on menu based etc, rigol info on the lowest status (where you put the program version/date/time) to tidy up the main UI so we can concentrate on what we are dealing with, in this case i think is the Vrms value(s). just my 2 cents.
