Please allow personal accounts to purchase more space

3 TB used to be a lot, but things have moved on, why hasn't Dropbox (in this area)? The ability to add more space would literally transform this into an amazing product again for me, forward thinking and for the users like the old days. Please make Dropbox a bit bigger for personal use - as a customer who's been with you since the start I try to appreciate all the work that the team puts in, this would be the biggest possible improvement I think! Best wishes.
