Selectable text on headings and labels.

[jacksonrayhamilton]

Would you consider restoring the ability to select text on headings and labels?

I see that it was intentionally removed in #44 and #54, but the reasoning that it "makes the package feel a little more desktop-like" doesn't seem very strong to me.

Sure, lots of "desktop applications" don't allow selecting that type of text, but I expect that's because it usually isn't important enough of a feature to warrant implementing. Whereas on the web platform we get text selection for free. So besides that "feeling," why not allow text selection here?

For instance, it could be useful to copy the name of a heading/label to talk to a friend about a setting in Atom.
