I don't disagree! ----- Original Message ----- From: [email protected] <[email protected]> To: Gerald Y <[email protected]>; [email protected] <[email protected]>; FlexRadioReflector <[email protected]> Sent: Wed Jun 17 00:27:55 2009 Subject: Re: [Flexradio] Click tuning with a Locked panadapter operatation
Gerald Thanks for the update. You mentioned that the pretty betty GUI will be included in the next release but will the "Classic" flex GUI still be an option. Call me dull, but I kind of like the classic interface. I have used pretty betty but find Some of functions more legible and easier to operate in the classic interface. Don't get me wrong, although pretty betty is a feast for the eyes, my personal preference is the classic interface. If anyone concurs, please speak up. I have stuck my neck out and have "broken the ice". Is it just me?
