You will probably come to despise me in this section, yet... another feature request.
In the small popup as per discussion title, an extremely simple "+/- % on traded amount" would be welcome.
For example, I traded 90, the bitcoin I bought are now worth 99, it would say "+9 (+10%) from traded amount".

Also, an aggregated percentage of all trader (BTC/BSQ) + miner fees, compared to traded amount, would be nice.
