Hello Sebi,
Before I start with the nitpicking, I should say that the hard work you put in is overwhelming positive. Thanks!
The following stuff has mostly been said before, but I figure that multiple posts let you know what people care about. It would be great to collapse the inventory view to card name only, just like the previous version of deckbox. While there are times that I would want to see all my different Giant Growths listed out, I usually just want to see how many I have.
When the only difference between cards is the date added, I would prefer not to see them displayed separately. Others might not like this idea, but I would suggest that when I add a card, every card in my inventory with the same name would have its "Date Added" field updated. That way, they would be grouped together. The new card entry interface is a bit confusing, but I'm going to give it time. There is a learning curve to everything, and I may end up liking this better than the old one.
Anyway, here are the two main points of the above paragraph. When I enter a new card, I'd like to see how many I have in total. And I would like to view my cards grouped by card name.
I don't know how to improve this, but I don't quite like that tradelist entries with unspecified editions show up as separate lines in my inventory. It looks like I have more cards because of the extra lines. More importantly, I don't really want to specify editions. Consider the following example: I have 4 revised Wanderlust and 2 4th edition Wanderlust. I only need 4 total, so I'll trade 2. If someone is looking for 2 revised versions, they could have them. Or if someone wants 2 4th edition, they could have them. I don't want to miss out on any trading opportunities by specifying editions. Basically, I want to make sure that people who want a wanderlust can find me no matter which edition they want. Of course, I know that no one actually wants Wanderlust;)
A couple of actual bugs (I think).
-When pop-up windows (such as the Edit Details interface) have scrollbars, the window disappears when I try to click on the scroll bar.
-Some of my cards (Phyrexian Walker, for example) display a decks icon indicating that they are present in decks. Other cards (Careful Study) are in decks, but do not show the icon. I couldn't think of a reason for this.
-Also, I think card entries should go away when everything is set to zero. I have two entries for Phyrexian Walker. One has 5 inventory, 1 tradelist, 0 wishlist. The other is all zeros. That may not be an actual bug, but I liked the old method better. I'm using windows 7, firefox 17.0.1.
Finally, I'd like to be able to sort by tradelist and inventory counts again (which only makes sense if you can group by card name). I generally trade cards when I have more than four, so sorting this way helps me keep my tradelist updated.
Okay, this is my last edit - After using the add cards widget a little bit, I think it's great. I just wish that it didn't add a card immediately upon selecting the card's name. Can you make two versions? A quick-add version like the one in place, and also a version where you have to click apply before anything hits inventory. That would be fantastic.
Thanks again - this is an amazing site!
