We’ve just deployed AppVeyor update introducing paging, filtering and tagging on Projects page!
Default page size is 10. You can change page size on profile page: https://ci.appveyor.com/profile
Tags can be specified on General tab of project settings (at the very bottom of the page):
Enjoy!

AppVeyor founder and developer
