While the effort in general is obviously great, I still want to point out that browsing the purchased bundle is a huge pain and it would be great if you could improve that. Either by making the bundle searchable from the purchases or by making your system aware that a game got purchased as part of a bundle when you visit the game's page (possibly by offering additional download options, so that one can download the game as one bought it with the bundle but can also still buy it, in case it e.g. offers Steam keys that weren't included with the bundle).
