Previous supercoin block explorer was way, way better, but the team decided to give up on it, 'cause it's more expensive.
One of the supporters was willing to pay for other one, but it seems he/she changed his/her mind.
We can't blame the dev team on that one...
As long as the community is not able to support the development team in a financial way, we should be thankfull for whatever sollution they come up with...
But I agree, the blockexplorers by Blockexperts aren't that great...
