This is being considered.
However, I'm hesitant to add new "fancy" features (may be not fancy to
you, but definitely to many others). Every time I introduce a new
option, a few users are happy, but then I face the consequence that
increasingly more and more people are saying Tagxedo is "too
complicated". I feel sad when people say that, not because of ego or
anything, but because some teachers or students will now be turned
away from Tagxedo just because others said it's too complicated.
That's my rant of the day.
