When placing parts and sub assemblies into assemblies a lot of the time you are either placing an item you have just created that's open or have recently created or there are item that you have been placing in quite regularly. There is no way to access these recent items to place in even though the welcome screen has a recent items. Instead you have to keep going through the folders to find theses not very productive. I think this could work in several ways and would be good to have all these options.
1. An extension of an earlier idea of mine is to have a list of recent items on a browser tab in which you could drag them into the graphics window.

2. For items that are open you could drag them from the tab into the graphics window

3. when pressing place you could tick a recent items box which would then display all the recent items with no folders.
