I have set up two instances of Device And User for customers in the last couple of weeks - before anybody jumps in and says “Device And User Is Unsupported” - I know! Really.
But are you interested in hearing about GUI inconsistencies and how do you want me to tell you all - Bug Report? Post Here?
Yeah Device and User GUI differences are interesting. From what I’ve used it’s definitely workable, like when editing a User it doesn’t have the floating pull-out menu on the right. And you can always access the regular extensions if applicable in your use case by typing in ?display=extensions at the end of your url.
Ok - They are not big deals but I think they should be easy to fix:
User - Once you click on a User, there is no way to get back to the Users other than through Applications -> Users - Devices and Extensions (when not in D&U) both let you select a different Device/Extension from the same pane - not User. You have to click-out.
User - You can set it to display all the extensions a million times, but the next time you go in (see above) it is reset to display only 10.
User Management - Same thing - select Display All and it always defaults back to display 10.
