Portfolio information and graphs
I think it would be pretty cool to have a main menu the user is dropped into that shows the total value of all coins and tokens and all wallets with a graph of each cryptocurrency similar to stack wallet.

Also it would be nice to have mobile widgets that show the same information for quick viewing like what CoinMarketCap has (off by default of course to not comprimise security).

If the team is interested in this idea I'd be willing to draft a PR.
