QuickOffice Pro HD — an app which takes not only its feature-set but its naming conventions from Microsoft Office — has gotten a big, big new feature. Now you can not only edit office documents, but you can track changes and comments in DOC and DOCX files.

Lawyers, editors, authors and anyone else forced to use office on the Mac or PC can now do their work from the bar or bus, as God intended.

Quickoffice Pro HD is one of the App Store’s best third-party office suites, and until Microsoft Office hits the iPad, it’s the best way to view and edit Word and Excel documents on the go. Its latest update adds Powerpoint editing to that, in addition to native email support, an enhanced visual interface, and more.
