Similar to the stretchable accel, rit. lines that can be fit across multi-measures, I'd like to see a stretchable expression text line that can be activated by a key combo like expressions and used for long crescendos or diminuendos that cover multiple measures. Even thought the cresc./dim. are non-functional, there are many cases when the extended words are needed. Having a way to drag the word across multiple measures and have them retain hyphenation (or add additional dashes as the words stretch further) would be a great tool to have. Having the text editable and the length variable would really make it work well for users.
