1) Pressing a letter repeatedly doesn't move to the next item (installed program name) beginning with that letter, so it would be nice to have this feature implemented.
2) Unlike Add/Remove Programs, after uninstallation the list doesn't seem to refresh automatically. One needs to open some other page and then view the Uninstall list again for the uninstalled program's name to disappear.
3) Options to Rename and Delete Entries are fine, but what's sorely lacking is an Edit Entry option.
