No tuplet tuplets.
Try this: select a quarter rest, and press ctrl +3 to make a group of 1/8 triplets, enter the notes, say A, B, C. then select the first triplet (the A) and press ctrl+3, it will break into 32nd note triplets with a 32nd for the a and two 32nd rests, however you will be unable to enter notes in place of the rests. if you try, something unexpected happens.

Nested tuplets are yet not implemented but there is already some code in the works.
