Hi everyone,
I just found under the Preferences in SD 4 that you can change the weight and colour of the box that highlights when you have something selected. Ever since I started using RSD and then SD I have wished for a way to see the selection outline better. Thank you Coffee Cup for this very useful setting!

Recent change after several requests.

I wonder when we'll see a change log for this latest version?

@John

Where is this located?? I'm with you that it was needed. Change logs come and change logs go, but, they don't come every time there are changes which would be nice.

Actions -> Preferences.

I found the setting under the main Preferences section, Site Designer->preferences.
