This was a huge amount of under-the-hood work, as you may have noticed on the time gap from the previous update. The app is now upgraded to a modern development framework, which will make future updates much easier for me. I have also focused a lot on performance improvements, as well as usability improvements, especially on smaller screens. No huge new features this time, but with the new framework in place, I can now focus more on exciting new features, and less on boring maintenance tasks.

Reworked the entire app to use MAUI instead of the now outdated Xamain.Forms framework, making future work on the app much easier.
Reworked the authentication system on the web page. This means that you may have to re-create your JetReader.net user and/or log in again after updating, but it will be more stable and more secure now.
Improved performance throughout the app, especially on pages with lots of images.
Improved usability when connecting to and synchronizing with Calibre.
Improved options for cover image sizing, and added separate options for the home page and the library.
Improved dictionary popup functionality and design.
Improved styling and design to work better with different screen sizes, densities and font sizes.
Added eReader friendly spinners that will be used instead of the default loading indicators when High Contrast theme is selected.
Added options for which information to show in the book details view in the library.
Added a cover image 'loading screen' when opening a book.
Added a theme switch in the left side drawer menu.
Added drag-and-drop support when re-ordering stuff in the sequence picker popup.
