the topic says it all: i suggest a feature to easily enter foil cards.
Ever opened a collectors booster display? You want to add a lot of foils to your collection!
At the moment having to "right click -> add foil -> click the little plus" are just too many clicks, it takes a lot of time.
In Collection mode there should be a "+" and "-" button similar to the ones already there to add foil cards. It could be optional to activate in the settings. (They could be in another corner of each card in the gui or another color or something.)
Best Wishes, Meilleures salutations and thank you for the awesome app.
