Cool new update sebi , I was a bit shocked when all the colors were gone, but as soon as I realized the difference between deck idea and built it all comes together.
The cards automatically matching to a specific card in a collection only if it's the only one feels like it creates more work, although on the other hand, before I had to manually check each row to see if it picked the correct one. On the plus side, using the quick-menu (arrow) -> matching -> owned and picking the correct card seems very quick. Would almost say it was faster than before to correctly match 10+ cards in a deck I imported..
A suggestion:
1) To auto-run the 'match to inventory' after the 'add card list' function has been used. 95% of times I import a complete decklist at one time, running the 'match to inventory after this would save me a few clicks.
2) A setting for the auto-matching when several different cards are present, for example a) newest printing b) oldest printing c) complete playset
Good Job, change is always scary
