Is to thank Adobe, as before myself and roommate had requested to have swatches show a border around the one you select.
Before when you click a swatch, it will not show a border around it so you do not know which is the last one you clicked on unless you look at "recent swatches", but problem with it is that the recent swatch does not show you side-by-side comparison with all the other swatches in the group.
Now with new cc2020, swatches show a border around it when you click it. Ahoy!!!!!
excellent addition by Adobe and many thanks for doing so.
We do notice that however nobody else on internet has mentioned this small upgrade when talking about new cc2020 features. perhap someone who makes posts or videos about newest features can add this to the list 🙂 🙂 🙂
