In the context of revamping yast2-users, I spent some days looking for an alternative layout that could help to improve the current UI by reducing the number of tabs and grouping form fields to make better use of available space.
However, due to our resolution constraints (UI must fit well in an 80x24 terminal) and some UI library limitations, looks like there is not too much room for big changes and our best bet is to keep the layout almost as it is, just making some necessary adjustments.
Summarizing them a lot, those changes will consist of adding a top menu bar for making easier the user navigation, moving all settings to the same dialog, improving filters by using a popup, making small changes in forms, and adding some summary views.
Of course, nothing is written in stone and it would be nice to know your feedback and/or ideas too. So, please, keep reading the following links if you are interested and tell us what do you think. Is there anything we overlooked? Some other ideas we should evaluate?
