Currently you have the preview button when using 1d input on the formula and Maple response areas.
The default behavior of the preview is to send your response to Maplenet and return back a MathML version of it. In this process Maplenet will sometimes do simplifycation that is unwanted.
In the Maple response area, you can account for this, but not in the formula response area.
It would be nice to include that too.
