After some weeks of use, my only wish is that a new firmware would fix the "Intensity Adjust" feature so that when you turn the knob the intensity would immediately adjust unless, of course, we are in some menu mode where it is used for selection.

I hope Siglent will put some attention to this small but important for user-friendly-UI detail.
In early firmware versions (only for the SDS2k back then) the "Intensity Adjust" knob did exactly that. Many users (me included) didn't like that, as this control is used a lot for selecting items and adjusting values in the menu system. Many of us inadvertently changed the trace intensity quite often. Especially people like me, who virtually never change the trace intensity, started to hate this feature. I certainly did not miss it, when it was gone at one point - but I never requested that. Quite the opposite.
When I noticed there are still people who expect to change the trace intensity at any time without digging into a menu, I sent the following note to Siglent:
The universal control knob is labeled “Intensity Adjust” on the front panel of the scopes, but the intensity can only be adjusted when the corresponding menu item on page 2 of the Display menu is selected. I for one like it this way, because I rarely ever adjust the intensity anyway, but some folks seem to consider it vital to have an intensity control immediately available all the time. Dave for instance uses it a lot whenever he’s looking at intensity graded waveforms. Maybe add another menu item to the Display menu where users can chose whether the permanent intensity adjustment is active or not.
This was the 4th of December in 2017. Quite obviously, this has not been implemented yet, but it is on Siglent's todo list and up to now, it has not been declined.
