Give up trying to improve yahoo mail if you don't have any idea what your doing especially if you don't use it yourself. First you limited storage space. After that switching from Drafts and attachments to documents is stupid because now every attachment now documents has the same attachments now documents. That move just doubled or tripled or more our bytes depending on how many attachments now documents I have, almost impossible to delete some and not all. Most people I tried to explain this don't use it much because they use cell phones I don't and never will so I don't think it effects them. I did use it 6+ hours a day 6 days a week but now days

as frustrating as it is after losing a lot of things I stop tired of trying to save space without deleting more than I want if not impossible and then sometimes the photos that I wanted to delete magically appear again that I don't want.
I find it hard to believe that this has continued for so long it's really bad but if people don't see it, will never know till it's too late and very difficult to fix.
