@muliswilliam — discussing in Slack thread with @Pavneet-Sing @jamesmudgett @nuo-xu. I believe they might ping about some updated copy for that modal.

The UX and UI of the aurora dialog needs to be updated for desktop

• Add "Don't show again" option and hide the dialog if user checked this option
• Move the links under the open dialog buttons

@muliswilliam — the text of the modal looks good. One design nit: looks like uneven spacing between the top of the CTA button and the bottom of it. Should this button be vertically centered between the "Don't show this again" box and the two strings of hyperlinked text?
