Michael Grothause of TUAW on improving the Mac App Store:
2. More options for sorting your purchased apps.
The fourth button on the Mac App Store’s menu is the “Purchases” button, which lets you see a complete list of all apps you’ve purchased. It’s a great feature that enables you to quickly re-download any app you bought and later deleted from your Mac. However, right now there is no good way to sort through your purchases. You’re limited to viewing them in the order you bought them, most recent to oldest. It would be great if Apple could add additional sorting options including alphabetical, price, category, last updated, and more.
Sometimes I don’t get how Apple arrives at the decisions they arrive at. Who thought it was a good idea to not a way to sort or remove things on this list? Every app you even installed shows up, even the ones you tried for five minutes and hated, and there is no way to remove them. I haven’t heard if this is fixed in Lion, but it has to be fixed soon.
