I am entering this after seeing a question posted on the mailing list about having tables within SF text fields.
There is an extension called PipeEscape that allows for pipe characters in parser function arguments avoid being interpreted as an argument delimiter. This works great if manually used in SF text fields.
Would it be an idea to have this code actually incorporated into SF forms? In this way you can have tables, galleries etc in SF text area fields without the user having to manually insert (or even being aware of) the PipeEscape extension markup.
