I wish there’s a way to upload image(s) including PDF thumbnails on the same post. Sometimes we need to upload multiple images and add comments referencing each image. It would be a nice feature to upload as one post or comment rather than uploading 5+ images, then add comment on a separate post. This becomes a really long thread.
This is one feature I really miss about Basecamp 3. Other than that, love Asana so far.
