When I put my parts into their position, often they have to be rotated by a certain degree. But when I'm using placement, it will by default rotate around the origin of the whole project. When the project is a little bigger, this is not a good thing as the part will completely be moved out of its position.
To make life easier (that, what we're using CAD, true?), I'd like two features:
* a context menu entry (RMB) "copy coordinates of mouse pointer to clipboard" - which can be pasted to the placement dialogue in the next step, and
* a "rotate selected item around its midpoint" button in the placement dialogue, which will automatically calculate the midpoint and insert it into the placement dialogue. This button can be deactivated in cases where the midpoint calculation is too complicated, but there is no problem with cylinders, cubes, balls etc.
