The "My Games" tab

All Excellent suggestions, that page is a source of frustration for us as well.
It is currently under review and we definitely have plans to update it.

5. Some other sites simply have you put in your code, and then it automatically identifies what game it is. This would be even better than having a drop-down list.

We have a design on a remake that will do something similar to most of your points. This one is sadly impossible. Because we import keys from different third-party developers, we can not be sure that two keys will never have a duplicate. I don't think we have any now, but it is better to make the system robust once we remake it.
