Perfect fit for our team

We use Ziflow specifically in reviewing our product materials. I wish it was easier for someone to learn the commenting features - it can be a lot to ask them to watch the Ziflow tutorial (10-15 minutes) or schedule time to go over it with each person. It's great for getting really zoomed in and figuring out the details, but this means that sometimes edits are hard to notice between versions. There should be something in the upload feature where you can reflect this more. We've gone around this by adding boxes around areas that are changed for reviewers to quickly approve the appropriate changes. Even small features like a spell check option or MLA/AP style check or if a word should be hyphenated would be great functionality. Could we add this as a feature where we can teach the system what words are needed for our style and it catches any incorrect punctuations or spellings of those?
