I cannot see any way to apply an opacity to text colour - is this so? Despite loving Layout, I have to say the text handling generally is pretty awful.
Labels are far too complicated with multiple levels of clicks.
I also really miss the ‘Paste and Match Style’ cmd-option-shift-V which I use in lots of programs. For pasting in text copied from elsewhere ready formatted it is invaluable. With Layout, I have to past the text somewhere, select, format, copy and paste again - tedious!
