A minor suggestion. When you add a game by barcode, but the barcode is not in core, you type in a title and do a search. If the game is still not found, and you click the add button, on the game information screen the information you had typed into the title field is gone. (When adding a game by title, the information is preserved on the game information stream, saving the effort of typing it in again.)
Yeah, that is a known bug. Will be fixed in the next update.
