It takes a really long time for the full list of "Fields Used By" to load in Field Management after you click on the "And more..." link. There's also no indication that it's actually loading after you click. So essentially you click on the "And more..." link and just hope that your click actually registered.
It'd be great if the load time could be signficantly improved, such that if you click on the "And more..." link, the full list appears within a few seconds. Or if that's not possible, it'd be great to add a spinner or some indicator to let the user know that the list is indeed loading.
