Hi, The nautilus "Open Location" dialog looks very similiar to the gtk+ file chooser "Open Location" dialog already. The only substantial difference is the width of the dialog. It would be good if we got them to match exactly.
Created attachment 121373 [details] make open location dialog width be 30 chars
I commited this upstream, we'll get it in the next nautilus update. Closing RAWHIDE as it'll eventually get there. :)
