My main ideas are:

Maintaining compatibility with Ethereum

Important protocol upgrades

Features that are already in development:
ERC223
new token standard that solves a security issues of ERC20 that caused loss of $400,000
DexNS
service for smart-contract upgrading and automated ABI accessing
ECNS
a port of ENS smart-contract is already developed and it will be deployed soon

For investors.

Let me share my ideas.
