Allow choice of "microphone" type and placement of that microphone in key locations on the "speaker". (e.g., center, near edge, edge). Not 100% sure how useful this will be (for me) and if I'll like the results, but it seems to be common feature of many modeler (even low end units). Not sure if this is an important feature (relative to many other, clearly important bug fixes and feature requests). As a workaround, there are software only solutions that let you generate a custom IR, but it's a slow, tedious process to test those out on the Amplifire (versus just changing a knob in the editor).
