Better support for foldables

I really enjoy using the app on my foldable phone (Honor Magic V3), but unfortunately not all views and functions are optimized for the foldable or work properly. For example, if you press the magnifying glass in the top left corner to open the search, only two entries are displayed. Although you can scroll and find multiple entries, only two are displayed at a time and the space below remains unused.

I have encountered similar display errors several times in very different places but can't recall them now; as soon as I encounter them again, I will add them here.

It would also be great if the app automatically switched to the "tablet version" as soon as I unfold the phone with the app open. Currently, the app starts to fill the large screen, but only the version for external screens is stretched. If you close the app and then reopen it, the correct tablet version will be displayed.

Overall, the complaints are on a very high level, and I am very grateful for how far the app has come.
