That kinda too. Though the computer-keyboard-numberkeys are only meant as a quick fallback, if you’ve mislayed your MIDI keyboard. 
It’ll also prevent running several Samedis for more pads, because they’ll all react to the same key then. [Edit: Actually, no, but only the active Samedi window will respond to the key…]
I don’t see making the app more complicated by allowing to config the computer-keys. People without hardware MIDI controller can run MidiSynth and have a full costumizable keyboard.
