need "go to folder" and "find dependencies / references" for user-driven library search

It's great to be able to search the library from the "open" + button. But, there needs to be a context menu item to go to the parent folder, like there is in the Library Admin Tool. And there needs to be an item to find the references/dependencies...

Don't execute data functions when required input data is empty

Many data functions you want triggered from markings. However, when nothing is marked, empty inputs are sent to the DF which causes errors. So you have to create specific error handling code for TERR to detect # rows for input and send out empty d...
