I held off on Windows 10 for as long as I could until Adobe, and therefore my job, required it. Now this nonsense. I hope this isn't the start of them joining on the web DRM bandwagon.
Inkscape now supports multi-page documents! The PDF importer was also recently overhauled.
Inkscape at this point is the “hold my beer” of PDF editors, able to edit absolutely anything on the page.
Only problem is Inkscape can't import or embed PDF fonts. It can convert text to paths during import, but that's it.
