Suggestion on improving navigation of ChatGPT chats

Some of this has been incorporated thankfully. Such as the memories, which sometimes does okay with AI making its own memory comment (I find the feature with looking over all chats extremely helpful at this point, thats’ a game changer).
But, as a developer, I am still finding that trying to get to chats within the same chat and same session is a real pain. Especially if you have a large amount of code to deal with. Currently the down arrow is strictly for going to the very bottom. There really needs to be 4 arrows. So Very Top, Up one post, Down one post, and Very Bottom. This would drastically improve getting through the noise.
Also, Having an AI hierarchy tree for each chat session would be a massive game changer. So, think like the chat session that has posts is like being on the ground, but you could get a birds eye view of all the posts in a summary in that one chat session and all AI would have to do is create those one line title summaries to show what each post references in that one chat session and having a way to expand it or to immediately jump to it in the chat session.
Even furthering of the concept that each post should either have a number or a title, so a user can just type in chat to go to that in the chat session. Some way of referencing the posts in one chat session better.
Right now, the problem really isn’t about finding or referring to chats across all chats sessions… The problem is still with being inside the chat session itself.
I hope ChatGPT engineers see this.
