Build 39 of ASIAIR v2.0.0 Beta now allows you to tailor the size of the GUI. (Display Zoomed in Personalized Settings.)
At 125% zoom, you no longer have to use your pinky or the Apple Pencil to change the Slew Rate slider on a 12.9" iPad, for example. And you can once again read the RA and Declination values.
The images in the windows are not zoomed, just the GUI elements. For example, a camera Preview image remains a constant size that is independent of the Zoom level. You had always be able to pinch zoom the camera image, and you continue to be able to.
I found the 125% Zoom to be quite comfortable with a larger iPad, while the original 100% was squint-city. Ditto on macOS with a Mac Studio Display set to the next higher resolution from default.
150% could be useful if you have poorer eyesight, and also to be able to more easily read the Polar Alignment numbers, which almost require magnifying glasses at the (original) 100% Zoom.
The ADU values are now also easier to read at 125% Zoom. I literally had to use a magnifying glass with the earlier Beta. The icon to tap on for the planetarium appears to have also shrunk a little from a more squarish rounded rectangle to a skinnier one, which is good news for those of us who don't use it .
The App icon has also reverted back to the icon used in ASIAIR v1.9. I remember someone complaining about the messy looking app icon in the two earlier v2.0.0 betas.
The ASIAIR Zoom behavior works well too in macOS.
IMHO, definitely a better GUI experience than the two earlier betas, especially on macOS, where you have no ability to change the ASIAIR app window size.
