Thanks for the prototype!
It already looks quite nice & simple.
Additionally to that I have the following remarks:
* place the filter in the upper left corner (maybe we should get a css entry for search fields in general as they are also used elsewhere)
* Remove the string "Filter" and use prefilled text field to tell the user what this field is about (e.g. "User name or login")
* The "Remove filter string" button right to the box should be removed as it is in the same position where usually the "OK, now start the search/filter" button is positioned. This might confuse the user. What about removing this button completely? The user can still remove his filter entries directly in the field? This would also solve the problem that the icon to delete a filter and to delete a user are different.
* remove bullet points in the list of users
- How do I edit an entry ?
Just by click anywhere on list item except 'remove' icon
Do the settings shown slide open when I click on the page or are they opened in a new link?
Do we need to show "Delete" that prominent or wouldn`t it be sufficient to show it on the same level as settings?
- think about this dialog with 20 or 200 users, will it still
be usable ? What will scroll off the screen ?
I don't have solution for this if filter is not enough. Any ideas?
Concerning scalability: I would recommend to move the "add new user" link/button on top of the list (above filter) so it is always accessible in the same place.
