Re: expression for length of text layer

This would work for a mono-spaced font, but I think it would break down with a long string in a proportional font. There's a brute force way of doing this - you create a table of the width of each character (a dedicated font editing program helps). Then your expression just adds up the width of each character in the string. It's a bit of work to set up, but it's fairly accurate.
