This new message composer for the ExtenDT2 mailing list looks clean and well-organized. The project itself is fascinating — extending Design Thinking with new technologies for education has a lot of potential. When writing longer posts or collaborative academic emails, I often run into hidden/invisible text or weird formatting issues that mess up the final version. Has anyone else here dealt with that? I’ve found a useful tool that quickly reveals and cleans up invisible text and hidden characters. By the way, I use https://textoinvisibles.com for exactly that. Looking forward to productive discussions on this list!
