As a Tech Writer, UX tester, and newbie Inkscape user:
Regarding Bit Barrel’s comments, I agree about not having both ‘Save As’ and ‘Export.’ Confusing. Photoshop uses Export for saving pieces of the art such as paths.
 
Also, the User Manual (or Guide?)  looks very good BUT it is not searchable. It would be easy to take the current pages (.html or .xml) and import/convert them into a navigable, searchable compiled Help file (whether Web Help or compile .chm file).
 
And, even though I’ve set preferences to Remember Last Window Geometry, it doesn’t remember the dialog layout, i.e., Layers Dialog, the Undo Dialog, etc. ( Version 0.48).
