AH tokens appear super far down the list when either searching or otherwise, because currently alphabetical order is used and filed under P for polkadot asset hub. Sufficient AH tokens should likely be at the top of the list or even better highlighted/spotlighted when you search and/or registered assets (according to hydration?) should be at the top in general. The use case for this is (for example) users going to Nova to deposit USDT or USDC to AH from a CEX and it's very far down in the list if you search (e.g.) USDT and would likely be confusing for someone just looking to deposit stablecoins to Polkadot for the first time.
