Thanks for these suggestions that may appear or not one day. Meanwhile, I would like to comment the few ones for which there are already some workarounds that you may not have not noticed.

6. Sort Furniture list by more than one category

When Searchable list is activated in the preferences, the search field of the furniture catalog will let you search among furniture names but also categories, authors and keywords.

13. On-the-fly wall defaults

Press <enter> key when wall creation mode is active to be able to type directly the thickness of the wall that is currently drawn.

15. Hideable 3D View window

Reduce the attached 3D view to zero height with the separator between the plan and the 3D view. This won't prevent the 3D view to have a different size once you detach it.

25. Virtual Visitor camera movement without selecting the VV icon

You don't need to select the virtual visitor icon to change the point of view. Simply drag and drop in the 3D view, use the navigation arrows or transfer the focus to the 3D view and use the keyboard.

Hope this will help [:)]
