Filled polygons would also be nice.
Filled polygons would take more work to implement the UI for, but could form the basis of the arrow support actually. So - add primitive polygon support - perhaps closed / non-closed both allowed, we could then use that to define various arrow heads. If feeling brave, fonts could be re-done with open polygons (poly-lines) which could be rendered in one step to the screen - and this should speed up rendering a bit. We don't necessarily have to add a UI to support it at the same time as the file-format and internals support. > A filled arrow would be nice for making diode symbols, transistor > emitters and MOSFET > source pins. Indeed ;) Just beware - I'm working on a lot of re-factoring at the moment, I just wanted to ask and see if there would be any support for this feature. If so, I may implement it - if not, I wont. The -user list is probably a better place to solicit wider opinion as to whether people would use it, but I'm not ready to propose it there until I ascertain where it has support from the developers (and I have time to code it!)
