My one experience with Ultraplan has been not good. It took too long to figure out how to comment on the plan. The overall process feels sluggish to the point that I wonder "is this thing on?" I also don't understand the underlying mechanisms (when/how are files being shipped between my desktop Claude Code and Claude Code on the Web) which is not a feeling I like as a developer. I have thought about abandoning despite the slowness but I'm not sure what that would do.
