data model:
materials = { card_path: mat_dict, ... }
cards = { card_path: card_name, ... }
icons = { card_path: icon_path, ... }
- duplicates are allowed
- the whole card_path is saved into the combo box widget, this makes card unique
- sorting happens on adding to the combo box widgets
a data model which uses a class and attributes as well as methods to access the attributes
would makes sense, like some material library class
this has been done already by eivind see
