Timeline - mention has been made of difficulty in seeing the Active Take information due to its grey colour. I find the same applies to the Ruler above the timeline. It is also difficult to see due to its dark grey colour.
Editing Toolbar - We have taken a step forward in having visible buttons again for Rippling etc. But on my 24 inch screen they are much too small. And the highlight black colour doesn't stand out from the black background. The highlight colour needs to be something that stands out like yellow or orange. But my biggest disappointment is the time boxes at the end. We've gone back to what they were in MS12 whereas I found the change in MS13 much more useful when editing. In MS13 the boxes showed the length of current active clip, length of any selected area, total project length. The active clip length changed as you edited a clip so made it easy to adjust a clip to a specific length.
