Practical ChatGPT tip I wish I'd thought of earlier: I've started replacing a lot of the individual SourceDocs in my projects with organized ZIP archives of the underlying files.
I can keep substantially more project context available to ChatGPT while making the Sources section much cleaner. Instead of maintaining 20 different context documents, I can organize the actual material into a few logical archives and keep adding to them.
I originally created SourceDocs partly because I needed to compress a project into something AI could work with. I'm realizing I can increasingly just preserve the real source material and organize it well.
If you use ChatGPT Projects for serious long-running work, this is worth experimenting with.
