Is it possible to have text that is being entered, instead of expanding the text box down (which is bizarre and usually doesn't help) can the text box be set to expand to the right, i.e. in the natural direction of text flow. If this behavior needs like a toggle or something that would work too. Example:
If I want to type some more text "for SLC only" into this text box…
Which I then have to resize, ALT-Z, and realign with other text in the area.
