Up2date's interface makes it difficult to perform certain tasks. For updating packages it works a treat, but for selecting new things to be packaged and/or removing item it can become a bit cumbersome. Something that was discussed on fedora-config-list was if system-config-packages interface could be coupled to one of the various backends to help with the interface. A redesign of the up2date ui to be geared more toward installation/removal/etc of packages instead of just updating would also be adequate.
