The only wallet as far as I know with lots of features and you can play a lot of things with contract address is "Myetherwallet"
But be careful this wallet is popular that's why so many people created phishing sites. Its safe but always check the url if its correct.
And many people didn't notice myetherwallet has eth to btc convertion its called swap.
I think the best fit wallet for you is Imtoken its an app and your safe from phishing it can store all Erc20 tokens.
