Hi Axel, ok sorry I wasn't understanding your original question properly. I thought you were asking for a new feature to have the center point of a circle to be displayed after it had been drawn.

So the problems with center and quad snaps not working on some circles are related to the other problem you observed when the size readout displays a generic x and y size rather than a radius or diameter value. When a curve is not recognized as a circle that will happen and also it won't have center or quad osnaps set up for it as well.

That can happen currently to circles that are pretty small, it should hopefully be fixed in the next v5 beta.
