This is a good resource page for math software.http://www.w3.org/Math/Software/mathml_software_cat_editors.html#Iezmath I figured I would point you at a list that might have something that meets your personal criteria. I use EzMath for Synthedit Sdk stuff and a couple others found on this page for Synthmaker stuff. I'm also curious what others are using other than paper.
