On quite a lot of the screens in the MySource Matrix (when adding a folder asset for example) the Name Edit box on the right hand side doesn't get the focus for you to start typing straight away. This is the same when editing the contents of a page and you add a table the little window that appears none of the edit boxes have the focus.
Also setting the OK button on some of the screens to be the default button might help as well.
Just a little thing that might make the creation/editing of assets a lot quicker.
I'm pretty sure there is a feasture request in the bug tracker to do with the Name box getting focus when creating. So, we know we want to change it - we just need to find the time
