Makes sense. My worry would be people try to deposit erc-20 directly to tomodex without knowing it needs to be wrapped.
Maybe if I could suggest on the tomodex funds page a column that says Tomo and Ethereum and then the wrap /unwrap button next to it.
That way coin name is seamless, and if people try to deposit erc-20 it shows up as balance in the Ethereum column. See picture as example
