in 1.4, the keyboard focus is token by the tree, so that you can 
directly navigate with the keyboard inside the tree.
This is explicitely programmed by sending #takeKeyboardFocus to the tree 
morph but after the window is opened.
(see SettingBrowser>>open)
It can be easily changed to make the search field take the focus on open 
if it is the desired behavior.
but I don't know if there is a way to declare the focus owner before 
opening the window.

I agree
