Suggestions that give Cardano more utility and/or visibility

I came across an app on my Samsung Watch 3 for Cardano. Its an ADA tracker, very simple but fun to have on my wrist. It shows the current price and a 7 day and a 30 day price movement. It would be great to see this app or another app give more data like the next epoch. Better yet a way to use the watch to transmit ADA via NFC. Where is the best place to make these kinds of suggestions? Will the Cardano mobile voting wallet have a place to share suggestions like this?
