What would you get developed if you had developers?

(I will not post company name, website, or anything that can be considered as self-promotion. Besides, this post is about getting your ideas.)

Hello everyone,

I own a small company working on edu tech. We developed a successful Interactive Whiteboard (IWB) software, and now we're developing a new version of it. But, we want to hear what you want/need as a teacher/principal. It may be an app, a new feature for your IWB software, a management software, an extension to your SIS... anything.

1. What is a real pain for you as a teacher? (tech related or not)
2. What is something that you would start using today if it existed?

All comments and ideas are appreciated. Thank you.
