Swap options

The way swap options are laid out is slightly unfriendly.

Initially, when a wallet isn't connected, you see the above screen. I have previously feedback that the connect button isn't working. And when wallet is connected, you see below screen.

In the screen above, I think it would be better to have default option already selected. So instead of having nothing selected on "Pay with", I would autoselect AZERO there. And instead of having nothin on you receive, I would put CMN there on mainnet - or simply leave this blank

Once the wallet is connected the wording "Pair not supported" is just confusing. It would be better to just have AZERO on "Pay with" and then either have CMN as default option on receive or if "You receive" is blank then instead of saying "pair not supported" at the bottom simply say "select a token" just like the drop down arrow.

Also "Pay with" and "You receive" isn't consistent. It should either be

You pay - You receive

or

Pay - Receive
