As a user since v2.4/2.6 I would say my favorite and most usable UI was 3.x series (ie 3.5), with 4.1 being really cramped looking on my laptop screen, due to how much space the track progress bars take up and the widening of fonts, UI elements, etc.
My main input for UI changes in future updates would be to allow users to be able to hide the right and/or bottom (export) panels in normal mode, with some refining of the UI to have a ‘smaller’ mode where text and icon spacing is massively reduced to allow wider side-by-side comparisons.
In addition, I really miss the 4X comparison with the AI models like in the older versions. The UI changing every 6 months and removing features is frustrating for finding the best model, and the inclusion of the ‘Profile 1 vs Profile 2’ UI idea doesn’t make it easier for quick enhancements or newer users (of the update, or in general).
“Pro” mode should have every UI element visible as is now, and/or more like 3.5’s themeing, less colorful aesthetic but that’s just my preference.
Standard mode should be simplifying the visible options (ie, no Preview 1/2 swapping) unless checked off in the View menu and/or in the settings, like Second Enhancement and other options are.
If someone wants a Compact mode, then the new UI, could be used there, but I’m worried it’ll introduce other issues that didn’t exist before, like how 3.x’s UI framerate drops caused my Freesync screen to stutter and flicker, while prior versions didn’t seem to cause it as badly
I also would like bugs with the window height being jumpy on some systems to be fixed, on my Windows 11 laptop with Explorerpatcher (Win10 look), V3.5 and 4.1 can’t decide exactly what the maximium window size and scaling should be, and frustratingly adjusts depending on hover over. Not sure what’s causing it or if it has to do with my DPI scaling, but it hasn’t been fixed and I haven’t seen any other program have it
One issue with this new UI would be making it ‘easy’ to lose track of where the interface’s controls are if it gets too small, like with the Filter text + button in the example video. I’m also kind of got the awareness / focus of a goldfish, and if it’s easy to accidentally close the Upscaler settings + Model popup UI, I might end up forgetting what I’ve set and second guess myself lol. Having the panel / side pane system currently lets me constantly see the thing I’m focused on and to easily make adjustments + click preview again to see if the smaller changes were useful. I’m a fan of Proteus manual because it lets me ramp up the sharpening, or reduce the decompression etc
