Add pop-up dialogue close button for slimTV?

[gharp]

on slimTV as deployed at https://vep.cs.wisc.edu/slimTV/

Open New Document > Select text to upload

the pop-up isn't able to close :)

Not sure if that an issue in this repo yet though

Finally getting back to making updates! Sorry about the issue, though I think this one is by design. "Open New Document" should open a new tab or window that prompts someone to point the browser to a new document. Until they have specified a new document, there is nothing that SlimTV can do for them--and so, they can't close the pop-up until there's something to show for them. Or is the pop-up not going away even after you've uploaded something?
