Function app transform question

[Dirk.nl]

Hi all,

I was just playing around with the new function app transform function.
I have a question, but maybe already ask! (sorry)
When I have in the function app a linear equation and when I do (several) times a horizontal and/or vertical transformation I see soft function buttons Simplify and Form. Also for a function like X^2
When I use, for example, X^3 I don't see that buttons. So I can can end up the transformation, for example, with (X-2-3)^3-1-4. Because there are now no Simplify and Form buttons it is not possible to simplify the equation inside the function app.
What do I wrong? Or is there something wrong in the function app software?
