Thanks a lot for the feedback! 1) Thanks, I will fix that; I agree it is not clear. We accept pptx, ppt, and pdf. 2) With early users, we found that content creation of Word documents can happen relatively easily outside of Word; this is not the case with PowerPoint. There are a couple of great online Word processors, and GDocs does a good job of annotating text. PowerPoint is different because it is still the ubiquitous way to make a presentation, a piece of software which has few alternatives, and currently no decent solution exists for this pain-point. 3.) That's a good idea. We did boxes first of all, because it's a one-size-fits-all approach and we wanted to keep it simple. We will be adding more specific annotations (text, shapes, graphs, etc.) in the future. Thanks again for reaching out -- and feel free to email me (leo@kivo.com) if you have any more questions!
