For example if i have plugin1 and plugin2, in plugin1 i declare shortcut_types=custom1, in plugin2 i declare shortcut_types=custom2,custom3
If i add only plugin1 to D2-config, i can make a shortcut with type custom1. But if i add both plugin1 and plugin2 into D2-config, where plugin2 is added at last, only the type custom2 and type custom3 will be active. And if i try to add shortcut with type custom1 it will show error that this is not in the list.
