Before we were pre-generating a DNS request ID every time the
add tunnel page was visited. Now we have a separate endpoint for
generating the IDs only after the user indicates they actually
want to perform a TakingNames.io domain request.
The UI was originally written using fancy HTML checkbox toggle
hacks in order to make the UI very fast. It's cool but complicated
and difficult to change. In order to make updates to the UI more
quickly, I'm changing it to use traditional HTML with full page
reloads for navigation. It's not as fast but much simpler.
