[interfacekit] TextRequestDialog

Hi,
do we have a general BAlert-like window class with a BTextControl in it so that 
the user can enter a string and press "OK" or "Cancel"? I need this for the 
DialUpPreflet (ask user for the new interface's name). If not, shall I write it 
and commit it into some more public folder so that people can reuse it (but my 
class would be _very_ simple)?
Also, what do you think of a small function that helps positioning windows on 
the screen?
E.g.:
BRect get_window_rect_for_screen_center(float width, float height)
or
void move_window_to_screen_center(BRect *frame)
What about a small file that lists all available utilities in our repository?

Bye,
Waldemar
