hello, why dont you create an electrum based wallet for toacoin in windows or android if you can., your new android wallet cannot export a private key and i want that function instead of using qt. because i feel more secure if i have my own privatekey, but for the sake of using mobile wallet which is more convenient and portable, i hope that you will create electrum based wallet... 
Check out the roadmap: https://toacoin.com/roadmap
Here youll see that they are already on the electrum wallet and its 50% done:)
ow i see thank you very much.
