Analog scopes also have a blind time (during beam retrace).

yes, right, but the percentage is much, much smaler... DSO have blind times between 99.99% and 90% of the whole acquisition time.

Yes I know. For example it works for trigger holdoff setting.
But there are many many times when Navigation Knob does nothing. When you using any of on-screen-keyboards (MATH advaced function, option key typing...) Navigation Knob does nothing. And you have to use multifunctional knob that does not have fixed angle, so you cannot feel by your hand how much step did you perform. You have to be careful and stare at the screen while turning the knob.

Just open Trigger -> Type list (if you have all advanced trigger options it is better - more options there) and try to move three (or 4, 5, whatever) positions down (or up) fast. You cannot feel anything by your hand and cursor is laggy. So you have to wait, look, correct yourself and so on (or turn multifunction knob very slowly). :-/O
As for any list in right menu. Navigation Knob simply does nothing there. But it would be great if it will act as multifunctional knob. Because it has fixed angles and you can feel and hear number of steps while you are turning it, you do not have to watch at the screen and wait.

I'd also prefer right menu up/down buttons to scroll through lists. When there is only menu and no list opened - they will do nothing or will scroll "pages" of the menu as usual. It will be great if they would move cursor through the list (as does function key that opened the list, bit it does it only from top to bottom, remember trigger type list?..). It seems so intuitive to me: vertical list, buttons near have "up" and "down" arrow...

"So if a glitch happens in the part of acquisition memory that is off-screen, you'll never see it." But, can the oscilloscope automatically detect it?

The maskrange, work only for a screen/screen-region, would be great if in a post process, the oscilloscope could capture glitches off-screen (at memory).
Also it could be done with SW on PC.

I have not tried, I wonder if this can be done with the segmented memory... Although I am not clear if it is equivalent in a matter of wfrm/s.
i.e. What is the min. "death time" between interframe?

I wish the Navigation Knob would also do high speed horizontal position in normal mode the same way it does in delayed sweep and record playback modes.
I also wish that the inner knob had a finger indent so that it could be spun continuously (like many professional video playback controllers).  The way it is designed now, I find it to be almost useless and, instead, use the small horizontal position knob which has the same function but can be spun faster and with more control.
