Some links that might help sketch the outlines of what a “Drupal admin UI revamp” might involve.
At Drupalcon Vienna there was a lot of interest and preparation work done around modernizing the Drupal administrative interface. I wrote up a high level summary here. As a result this initial issue was posted.
We also discussed this topic during yesterdays UX meeting.
As a result, ckrina now proposes an initial round of research to learn and get inspiration from other systems. Mind you, this is the woman that brought us the redesigned status report page and is a member of the team that made the Umami demo that’s now in core. Good things can come from this!
Your help in researching these topics is very welcome. Have a look.
