Hi,
The FRONTEND team at Moodle HQ are working on a number of new things to do with usability and features for Moodle 2.7 and beyond.
To improve our development process and decision-making, we are focussing on producing quick usable prototypes of ideas early in the 6-month development cycle, before getting deep into proper coding.
To facilitate this we have a new site called prototype.moodle.net where we'll be publishing experiments and examples for you to try out and to give us feedback on. The site will be evolving over time with new projects and mockups. Also note that it's not comprehensive and doesn't include everything we are working on.
If you have some time, please explore the Moodle sites there and try out the new features, then give us feedback using the surveys or other methods provided.
Thanks for helping to improve Moodle!
Cheers,
Martin
