I think it would be very helpful if you could go into a single task and there was an option on the drop down menu to download all files associated with that task. Additionally, same with the “files” tab of a project. If there was a drop down menu in there were you could download all files for that project to your computer.
I agree, that would be very handy in some circumstances. However, I can also see situations where version control would be a major problem. If you have access, you could try a Dropbox or Google Drive link. That way, everyone can view the same documents in one place, and always have the most up-to-date versions.
