When you create a new application you have the option to use separate databases
At the moment tabbing out of the name field does not move focus to the Allocate separate test database.
It would be great if it would take the name of the prod database (in image above the field with name in it) and append Test. This would save a nano second for everyone who just wants their databases to appear next to each other in a schema list, and it wouldn't affect anyone who wants to use a more exotic name because they would have typed it anyway (especially not if tabbing from the check box to that field selected the text).
