It's been almost 4 months since I complained (to Rigol, of course) and this thread is dated from that time. At the time they said it was in the works and a new release should't take long (the support guy is excellent and even got me an R&D preview image of what was going to be final result).
You have a direct connection to the people who fix the user interface???
I have a couple of suggestions...!
Let's start with that damned multifunction knob that moves and makes wrong menu selections almost every time you press it.
eg. To change a menu selection: Press the menu button next to it, use the blue arrow keys to move up/down the menu to the item you want, press the same menu button again to select the item and close the menu.
Another way to do it would be keep everything as it is now but allow you to press the "Clear" button to select a menu item
as well as pressing the multifunction knob. That would only take about 1 extra line of code but eliminate a lot of frustration.
(In fact, there's no reason why they couldn't implement both of those things....)
Oh, and they could set up a system where people can make suggestions for user interface tweaks like this.
