I use TeamWork for most of my business task management, however am coming back to Asana for personal projects and am evaluating it for future business usage.
One thing that I am really missing is the ability to paste an image into the comment box and have it be automatically attached to the task. I used to do this on almost every task in TeamWork, to either attach resources or to upload screenshots pointing out issues etc.
I’d find Asana to be a lot more useful if I was able to do that here.
