Allow people to move cards from one list to another
People have different classifications for their cards. MTGPrice offers 'lists', defaulting to 'my collection'. Often, people will start putting in their cards without being able to separate them out. This can be remedied with an export/import, but any list other than My Collection doesn't have this ability.
I suggest you make it easier to move cards from one list to another. In lieu of that, I suggest you put the ability to export/import collections onto the other lists besides My Collection
This was done awhile back, so closing it out!
We do plan on adding the import/export options into the other lists as well. But seeing as the new lists are a fairly new feature that has been added, we have to take it one step at a time, in order to ensure nothing goes wrong in the upgrading process.
I don't have an exact time table for when this will be added, but it should be in the very near future, if all goes well.
