If I browse away from the Swapper to check a balance, change settings, I need to start the selection of assets from the beginning (default values) and enter amount(s) again. It would be practical if the app could remember the form values as long as they haven't been submitted (they can be cleared once a trade was completed for example). It would also be practical to remember the last few assets (including the chain) that have been recently searched and selected/clicked on, so you don't have to search them again to select them.
