BlockExplorer (preferably a format I already support in my other plugin since these things share the same codebase)
Expected payment rewards or a BlockExplorer that flags MN payments as such
Coin name
Details on their MN system (the more detail the better, Bitcointalk link works)
A masternode address that is currently active

EDIT: It would appear that UExplorer has no API for transactions, so I cannot easily support CURV
