Hello, all! Just a quick note to share that this idea is currently being worked on. There are a couple things to consider in this request and we will need to address them in iterations.
Our first step is to add word count to SpeedGrader for text entry assignments. Our currently plan is for this to be available in November.
Our next step is to do some additional scoping for how to accomplish this with files uploaded and viewed through DocViewer. More to come on this as we look into if this can be accurately and consistently made available.
