I think it would be helpful to have a notes section on the sidebar. We could take notes and leave to do items, so they don't get forgotten. Having them saved the project would be essential.
I'm curious what your prompt was. Claude is saying that nothing can be added to either sidebar or make a new tab in ZZ interface. I was able to create a pop up with a list but every time I add a new note it relocates to the center of the screen and has to be moved.
I can't recall at this point because it was a month ago, but it sounds like you are going through the same growing pains I first went through when I started trying to build stuff with Claude where it would repeatedly insist with great confidence that this or that could not be built in zz, only to eat its words an hour or so later.
Show it a screenshot of this so it can clearly see it's straight up wrong.

Todd can also send you a Dev Mode Knowledge Base document that you feed to Claude, which then smacks some sense into it and educates it on what is possible in this platform
Thank you Jes. Claude is figuring it out this morning.
