This suggestion for improvement
* regards editing svn properties (externals) in 'advanced' mode
* and has two subitems:
1. The svn property edit button has two divisions: "Default" and "Advanced". I always use advanced mode editing externals but 'default' is default and I have to open the drop down menu on the button each time. It would be very helpful for me (and others) if my last decision would be stored.
2. Editing the first property it is not possible in advanced mode. So if I want to add externals (for example from a given list), I have to create a dummy property in default mode and go back to replace this dummy in advanced mode by my list.
New->Other, then select "svn:externals" from the dropdown.
