Love it or hate it, Microsoft Word\u2019s Track Changes feature is often absent from Office-compatible word-processing apps for iOS and Android. With yesterday\u2019s Pages update, Apple added track-changes support to its iOS word-processor app.\nWhile the addition is greatly appreciated, Apple still has some work to do.\n\nTrack Changes is a feature many attorneys, editors, writers and others can\u2019t live without. I frequently receive marked-up Word files from editors and others I\u2019m collaborating with. I need to see the text they\u2019ve changed so I can accept or reject the edits. In turn, they need to see my edits. That\u2019s the beauty of Track Changes. The misery of it is when you\u2019ve got a long document with huge amounts of tracked changes, but that\u2019s another story for another day.\nWith the December 4 Pages update, Apple added \u201cChange Tracking,\u201d which is accessible from Page\u2019s drop-down tools menu. When someone emails you a Word document with changes tracked, you now see those changes underlined and in color. Pages gives you three viewing options: Markup, which shows all tracked changes including deletions; Markup Without Deletions, which excludes the deleted text; and Final, which accepts the tracked changes for a clean, final copy.\nAs you scroll through a document peppered with changes, you can double-tap each change on your iOS screen. A menu pops up and allows you to \u201cAccept\u201d or \u201cReject\u201d each change. When you\u2019re done, you can export the document back to Word and email it to your collaborator. In Word for PC or Mac, that person sees new tracked changes you added using Pages on your iOS device.\nThis is great news, but with one big downside: Apple\u2019s Pages app doesn\u2019t support comments. My collaborators often attach comments to specific changes they\u2019ve made. Until Pages supports comments, you have to ask people with whom you exchange documents to insert their comments directly into the text, so you can see them on your iPhone or iPad. (Apple posted a helpful feature compatibility chart comparing its iWork for iOS apps, which includes Pages, to Microsoft Office.)\nThough not as pleasant to use as Pages, Office\u00b2 HD, an Office-compatible suite of iOS apps, supports both Track Changes and comments. Also, Office\u00b2 HD is $8, compared to Pages\u2019 $10 price tag.\nSo thank you, Apple, for making your delightful Pages app even more compatible with Word. But in the next release, let\u2019s see some support for comments, please.
