that's easy on its own, get the pointer from the output of [struct] when  
you click on it. use it to change the color with [set ...... color].

you can't click and drag on data-s, so your other idea is better (and get  
the pointers to make the display look accordingly).
Once I did a sampler what I had an horizontal line of marks indicating  
places in a sample; also using [mousestate] to get the mouse actions  
(position in window + clicks) I could extrapolate where I was in the  
window, and what should sound.
