Dasher remembers sprint

Many times I wished I could paste sentence I just deleted. Or something I wrote 5 minutes ago. Dasher could remember last X texts and give people option to select one of them in control box. Another useful feature would be paste one of the common phrases. Every person would have their own file with common phrases. For example "Due to medical condition I can't speak, and I use this machine to communicate.Please be patient, it takes time to write." Again, these phrases could be inside control box. Maybe parsed from the file.
