my suggestions:
make the "Select Output Streamer" with a DropDown menu
example: (for if you don't understand what I mean)


and also:
a "make larger" and "make smaller" button
it's handy, trust me ^^
example:


and (if it is possible) make the objects convert automaticly without the "convert" button (for the lazy people)

and last: a "browse" button for opening an MTA file


ps, nice update already ^^
