Following my mild moan on Twitter about GoogleDocs editing functions, I said that I’d note down the feature from Word that I miss in GoogleDocs. https://twitter.com/CokoFoundation/status/1007631154797637632
I’m afraid I’ve not used Wax so it could be that you’ve already included these features.
The major issue I have is that the three modes of GoogleDocs (editing/suggesting/viewing) in combination with the “Review Suggested Edits” tool are not as useful as the four viewing modes of Word (Simple Mark Up / All Mark Up / No Mark Up / Original ) in combination with track Changes On/Off.
Editing/Suggesting is equivalent to Track Changes On/Off but the view modes (which are essentially previews in GoogleDocs) make it very difficult to follow what is going on once you’ve got lots of changes in a manuscript (I’ve recently seen manuscripts with 200-300 small changes).
The most frustrating thing is not being able edit a manuscript with tracked changes on in a manuscript in google docs without seeing all of the mark up. This is simple in Word (Tracked Changes On, No Mark Up mode). In GoogleDocs the only way you can see what the edited manuscript looks like (without accepting suggestions) is to use the preview tool (Tools>Review Suggested Edits>Preview “Accept All”). Unfortunately, this is a view only mode so all of the minor problems that are easy to miss in a busy tracked changes manuscript are hard to pick up - it’s very time consuming to flick between modes to fix missing spaces, grammar problems, rogue words/letters that didn’t get cut or extra carriage returns. The viewing mode hides tracked changes and again is view only.
Until recently there were also problems with calculating word count of the tracked changes document (although that seems to have been recently changed) and copying comments and suggestions over to a new document (again this looks like it has been recently resolved).
