This weekend we added two new features to the pidoco Prototype Creator: colors and permalinks. From now on you can choose the border and fill color for rectangles and ellipses to highlight certain areas of your prototype. We also added a semi transparent grey filling which you may use to create overlays and modal dialog boxes, similar to what you see on the screenshot.
For the second new feature we slightly modified the invitation dialog and added a new feature to the invite menu entry. In this new dialog you get three links, one points to a png image, one to the sketched html, and the third to the plain html version of your prototype. You can choose the page they will point to and copy paste the link into your wiki or send these links via chat to your colleagues.
