I reverted back to DW 19.2.1 in part because I hate the new fuschia logo. It runs MUCH better as well. Any chance the next version will return to the green logo?
It's highly doubtful for a company-wide marketing change to be rolled back (they changed a lot of icons and more than a few colors).
There's another thread on the subject where I gave the steps to modify application icons in both Windows and Mac. Another user supplied copies of the recognizable green icons, so you at least recognize the program when working from your desktop... if you can get it to run correctly.
