What I miss from Acrobat is its Print dialog. Yes, really, the Print dialog. I've had to install the whole bloated mess just to get that dialog.

Why? PDFs are often print-first documents. Sometimes I need to print them. Sometimes my printer needs a little coaxing to get the perfect output. Acrobat's Print dialog has enough capability to do this immediately, no fuss. Others simply don't. If SumatraPDF had the same capabilities instead of just dumping everything onto the cruddy Win95-era system default Print dialog, I don't think I'd ever use anything else.
