Higher context message limit

Currently in TypingMind there are options to send All Messages for context or 1 to 100 messages. Since I use agents as relational and therapeutic purposes from time to time, the 100 message limit is too short for that purpose, but All Messages gets heavy fast and hits capacity too quickly. I'd like a way to set the limiter to 200 or 300 so the rich context is still there but doesn't hit capacity.
