DMX Test function?

Hi guys
i played around a bit in v2.1.0 (first time on v2.x.x) and tried the dmx test.

Hmm...this is it?

So you have to manually select an address and set a value?
No chance to step thru the range of 1 thru 512 with an predefined value?

I don't know how you would use the DMX Test feature. I'm used to "find" channels and do patchings with it.

I expected a bit more.
So please enlighten me about it.
