Card/Token Viewer - Needs a search capability

Would be nice to be able to search not just for full sets, but to be able to search for say 'Goblin' and have it automatically choose all sets Tokens/Cards that have Goblin in them for example. It's hard to work out which images you are missing (specifically for tokens at the moment - there is the 'Copy/Paste URLs' option in the download cards that does copy a list of missing CARD images to the clipboard).
