another question:  

real life situation:  I am at jam session, where someone is saying the chords as we are playing..... can I create a blank file in MSP, where I can write in those chords/make a chort chart on the fly to save for later, rather than writing it down on a piece of paper?

Yes, you can do that.  I have never done it, but I can offer one way to do it (there are probably better ways).

Convert a blank word document to pdf and save it in Mobilesheets as (for example) "blank".

Then, if you want to "write" on it (annotate it), pull it up in MS and use the annotations to write what you want (either typing or you can try using a stylus).

Then save it with a name to remember and pull up later (and probably clean up and correct).
