TRADERS! a repetitive action I use a lot to modify market orders is first using mouse scrollwheel to get close to new price, then switch to keyboard to type it in.
but in this beta UI the actual price is no longer highlighted for me when I switch. I have to go from scrollwheel, then fully highlight the price (which is ALREADY highlighted) and then manually alter the price.
This is totally ok for 1 or 2 order modifications but as a trader we do hundreds of these often. In old UI this works seemlessly. In the beta UI it adds 25% more time to doing trading maintenance.
