Sometimes, you can end up in multi-line mode without noticing or forget to escape out of it and you end up typing gibberish in multiple places in your document. It would be great to have some sort of obvious visual signal to constantly remind you that you're in multi-line mode. Currently, the rather unobtrusive text in the bottom-left corner of the screen is the only notification. It's quite easy to miss as it is.
