Additional units displaying options for the Trezor

Hello,

I have a suggestion to improve the “problem” that some crypto currencies have a so high priced that you have a lot of digits after decimal place when you send small amounts.

There is a simple solution:
For Bitcoin and Ether should be the option to use the 0.001 units. For Bitcoin this is mBTC and for Ether this is Finney (mETH would have some negative connotation i think)

Another option should be to use scientific notation with E+ and E- numbers.

I know there are probably other priorities but this wouldn’t take so much time to implement into firmware and improve user experience a lot for high priced coins with small value transactions.
