When I want to use ui-if (anguluarUi) with ng-repeat (and I think it would be most useful there) I Get an error:
Error: Multiple directives [uiIf, ngRepeat]
I think that a filter should be used instead of ui-if.
ui-if was removed at least from latest version angular-ui but since angular 1.1.5 you have ng-if build-in.
