Icon choice flexibility

i updated my niagra app recently and I've noticed that the icon selection choice (in edit icon option) for an app is now a predetermined row of icons and I can't access the entire icon list. i vastly prefer the old version because it should be our option to decide what icon we put and not some premade category based option list. is there some way to pick the icons like before that I'm not aware of? please revert it to original if there isn't. thanks :)
