I just created the Moodle Tracker entry MDL-28198.
I tried to get the Moodle popup dialogs looking consistent. After spending a lot of work into the filepicker, quiz and help dialogs I arrived at the enrolment dialogs - and went nuts.
I get the impression that each Moodle popup is build different - different XHTML structure, different CSS, different images
Usability of the dialogs is similar inconsistent. For example some dialogs have "Cancle" buttons, some must be closed clicking on the "x"-close-button.
There are 5 enrolment dialogs - each is different. From the dialogs I had worked on I got the impression that they more or less use YUI Overlay structure and CSS. From the enrolment dialogs the "quickcohortenrolment" dialog is the only one basing on Overlay. The others are build different.
Please refactor ALL dialogs to offer a consistent interface (look and feel, buttons etc.) and use consistent XHTML, CSS and images.
Please, everybody interested in Moodle Usability and Look vote on the tracker issue - I hope somebody will investigate then.
I cross-post this topic here and in the "General developer forum" because I think this is an issue for developers and designers and not many read both forums.
