Navigation on NeoReader in 3.1

Hi, congratulations to Onyx on the new update!

Among the features of version 3.1 is the following:

• Optimize the PDF selection and zoom process, directly selecting the zoom-in area by dragging the frame

There was a problem with the navigation tab in NeoReader on 3.0: the zoom-level kept shifting, and did not suit the selected cropping scheme (https://help.boox.com/hc/en-us/community/posts/360076311732-Note-2-Issues-with-neo-reader-Natigation-crop-lines-don-t-match-what-is-shown-and-minor-bugs-)

Could anyone please tell me if the new version improves on the previous one, and how so?

(Is the navigation feature still available at all, or was it replaced with a form of selection-by-dragging?)

Thanks in advance
