Some possible features to get users more compfy

• Often in the Cesium² app, one can see different public keys. There is the Subtrate public key starting with 5..., the V2 public key starting with G1..., and I think it could be great for the users coming from CesiumV1 to see at least the first character of their good old public key.
• No "Page" tab as there is in Cesium V1 after clicking on registry. But will anyone misses it ?
• Last but not least, is there a web extention planned ?
