[Feature Request] Calculate Minimum Transaction Fee for each Block
This is a selfish request as I am creating a chart at the moment which needs this information and there is no historical source which I can pull the data from. I will recalculate the values myself but it would be really cool if the XMR block explorer advertised the base transaction fee for the block, even if it was an estimate.
