Several times now, I have run up against this and am guessing I am not the only one...
There are times when all of the selected text is not put into the stack item. Tonight, I wanted to put a section of a journal article in my Sermon stack. When I pasted it into Scrivener, the entire section was not there (the section comprised 2066 words).
Would it be possible to increase the size of text that can be put in a stack item?
