I guess I would like to take that a step further and should have been more specific. I do not want to simply integrate Office - and we don't use Office 365.
I would really like to be able to annotate as many file types as possible when grading Assignments - not just Word doc. That is simply the most common so I thought I would start there.
For example, with Schoology one can use their Document viewer for following file types submitted by students (and some/most of the ones I would want can be annotated):
Note: Our Doc Viewer supports the following file types--.doc, .docx, .html, .odt, .pdf, .rtf, .text, .ppt, .pptx, .swf, .xls, .xlsx, .mp3, .mp4, .mov, .wav, .wmv and many more. The submission viewer does not convert iWork files, but you may download these submissions onto your computer. Not all file types (e.g. media files) can be annotated using the Annotation tool bar.
I was curious if Moodle had something similar.
