Hi Bruno, I like the idea. I suggest you that you share it first in the Joomla User Experience forum to get feedback from other members of the community interested in the interface http://ux.joomla.org/forum. I also suggest you to provide a screen capture with the "before" and "after" look.

If you want to contribute a patch with the improvement you can create a new feature tracker at http://joomlacode.org/gf/project/joomla/tracker/

Thanks very much.

In fact, it is much more simple to solve.
Modify com_installer/views/install/default.php line 51
Change class= "form-horizontal" to class="form-vertical"

Hi guys,

What's the status on this one?

Thanks for reporting this. At this time we are only using github as the place to submit code fixes so I am closing the report here. The actual reporting of issues and testing fixes is still taking place on Joomlacode.

As it has been some time since you opened this issue can you please confirm that it is still valid with the current Master or Joomla 3.2 beta.

If it is still valid please can you open an item on the Joomlacode tracker in the appropriate area.
