Increase the export/print options in the Sidebar Instant app

[RyanBohan]

It would be great if there was increase the export/print options when configuring Export in the Sidebar Instant app

Possible improvements:

• Prepopulate the Title 
  • Instant App Title, or something configurable
• Turn on "Include selected features" by default.
• Include tool tips for users

Thanks @RyanBohan for the feedback. We made the update to standardize the component we use for export across the instant apps. For the next release we'll work on adding additional capabilities to the dialog and I think your suggestions make sense.
