@ Iván It does save automatically - that's why there is no Save button :) If you want to do a "Save As" every time then that's fine but not required.

I'm sorry the file dialog is slow - that's the phone, not my code. Equally the code is supposed to ignore multiple presses and not show multiple dialogs; I think that's a regression in the libraries.

Apart from the problems with gestures, I find that save and load options are a bit tricky.

First of all, changes in the list should be saved automatically on exiting. If I want to save my changes I have to press in 'Save As', find the actual list and overwrite it.

Besides that, when pressing 'Save As', it takes a few seconds to fire up the file browser, so it's easy to press again the button (thinking you haven't touched well the screen) and see two times the save dialogue (one after another).

The gestures don't work very well on the touchscreen.

Removing all categories, then trying to add an item makes the program crash every time.
