Copying and pasting a line of text into the title of a note often includes a return. This causes the title to appear to be empty, as if the paste has failed.
I know I could be more careful to select text without the return, but triple click to select a line is so quick and intuitive!
It would be cool if Agenda always stripped return characters when pasting into the title. (Perhaps Tab as well - though I’ve never had an issue with that.)
