I wish there was a /model setting to use opus/ultrathink for planning, but sonnet for non planning or something. It's a bit annoying having to swap back and forth tbh. I also find planning to be a bit vague, where as i feel like sonnet benefits from more explicit instructions. Perhaps i should push it to reduce the scope of the plan until it's detailed enough to be sane, will give it a try
