Ahoj!
I have only some small questions/suggestions:
* What is the meaning of the left text field (which contains: "Some text here"" in the mock up)?
That is an area where pattern description should be. For example: 'YaST development' - 'tools and libraries for developing YaST modules ... blah blah'. It does not work yet Currently pattern descriptions are not visible anywhere in the installed system, you can view it only during installation in software proposal (before you click on 'Details ...' view). Moreover, it is Qt UI specific as this feature was not requested for ncurses.
* What about moving actions into the top menu row? Then there would be just one navigation/action area.
It is there on purpose, because of easier navigation. Reason: if you want to change status of selected package and you don't remember keyboard shortcuts (+,-, Space and friends), you need to press Shift-Tab three or more times to get to the correct menu item. Now all you need is single press of Tab key.
* Is it really necessary to display the selected package group again?
Hm, you mean 'Package: ...' label under package table? No, it won't stay there, it will be probably replaced with currently selected package name (possibly with its version), it just does not work so far ;-)
* What about moving the filter in the left box above the box? This could save one box line?
Uh, I don't really get your point here, sorry. B. -- \\\\\ Katarina Machalkova \\\\\\\__o YaST developer __\\\\\\\'/_ & hedgehog painter
