I'm enjoying the beta very much and can't wait for it to launch properly! So far most of my nits have simply been me not knowing how to use the software well. However I would like to know whether it's possible to have mixed units in a document. For ex.: inches for the document & ruler, but picas/points for the panels. I realize you can enter any kind of measurements in the panel fields, but it's easier to see pt/px there, while seeing inches in the document rulers.
