zoom object

I launched the idea on “inkscape” there is a zoom button that allows to see 100% select the object
on synfig no tool.

(Message translated with Google translate)

good idea

Are you talking about that inkscape feature ? Zooming the Canvas

Yes exactly, is this button:
(with your link).

Ok … So from my point of view, you can post a feature request on the synfig tracker : "Zoom to fit selection in window. "

I’ll let you make the request.
