• KivyMD is API unstable as of now, it's best to use either the version I've used on my computer (1.0.0.dev0), or main branch. A lot of bugs are fixed in the main, so, unless something's broken, install from source, not from PyPI: pip3 install https://github.com/kivymd/KivyMD/archive/master.zip
• I've used a native filepicker instead of Kivy's (because kivy's picker is horrible). pip3 install plyer is required for it to work

python3 main.py should work. XML files for testing are located in the ./examples folder.

• A separate type for sending records between controller and view
• A more sophisticated error handling system, especially for XML parser (with SAX error handler). Seemed to increase the complexity of passing the error to the view a lot, so I've made a generic error message instead, because I was near the deadline on the assignment... Eh.
• A better way to call the app's controller (pyright's complaining right now)
• Binding data from the model directly to the view (buggy on KivyMD, see below)
• Fix the pagination (not my fault, see kivymd/KivyMD#1242)
• More coherent UI: input field validators, correct sizes for the dropdown menu, action bar based on the MD guidelines, better default window size, accent colors. Honestly, I tried to create a beautiful GUI. Now I couldn't care less. By the time I've finished this project I was (and still am) hoping I won't touch Kivy or KivyMD ever again - here are some of the reasons why:
  • GUI is very slow (maybe OpenGL on macOS is to blame, but generally GUI is very unresponsive)
  • Lack of updated and/or full docs
  • incoherent UI elements, lack of some basic widget variations. Generally you have to write a lot of boilerplate, even for basic widgets (such as dropdown input)
  • Touch emulation creates excessive input lag
  • KivyMD's binding system is very unstable, I had to rely on callback functions and lambdas instead.
  • The layout system is intuitive, but the position customization options are not - it was a hell to figure out how to position elements correctly.
  • The DSL of Kivy (.kv) is nice, but .css would've been nicer.
