i love Inkscape !

But some questions:
- i need to put a circle in a certain position inside a large rectangle. Is there a tool to get the distance from a point or object side ? Or the only way is to calculate it by the horz and vert rulers?
- is there a way to save a relative path for the imported images? Or do I need to remove manually from the xml saved file?
- i put a guide n the sheet and then i snap a circle(s): is it possible to move circle(s) moving the guide?
Thanks a lot !!
