Right now when a user navigates to a URL that is not associated with a page or the URL for a page that has been removed, you end up at an ugly 404 page located in /customHandlers/
As seen in this forum post you can edit the custom Handler's page directly, but my understanding this would change it for all apps, and doesn't seem possible in a Cloud environment.
It would be nice if we at least had the option of configuring the 404 page, similar to the Invalid permissions or Internal error pages. Especially if one of the inputs of this page was the originally attempted URL, meaning we could redirect the users if they were attempting to go to an old screen that was removed, but the content is now elsewhere.
Thanks!
