The original background colour of the dropdown menu's in PT12 such as inserts and sends are very dark grey/almost black. The DTouch dropdown menu is very light grey. Personally I prefer the original dark background as it is easier on the eyes in a low-lit studio. It's not a big deal but maybe something to take into consideration in the next update.
Thank you!
