Hello,
Thank you for your feedback.
Unfortunately I am unable to implement suggestions or create new extensions.
However, if you are using the Exchange extension, and if you can provide liquidity to a market by setting limit orders in that market, then you can use the shortcode: [wallets_exchange_market_order] with no arguments.
The UI will determine which currency pairs are tradeable based on the availability of markets on your system, and will show a simple UI with two dropdowns.
For more details see the relevant release notes:
💱 Easy crypto swapping UI, plus theme-able templates for the Exchange extension
Please let me know if you have any questions about this.
with regards
