When I create a new app in AI Studio, I tend to use some fixed system instructions to get a proper layout with a menu. This menu includes a manual telling how the application works and a list of recent changes. Both are quite useful for my users.
Now, updating the manual is done by asking for this in the prompt. It then updates the manual, regenerating it as Markdown and rendering it to HTML when displayed.
But the list of recent changes is trickier, as this cannot be extracted from the code as the previous code has been removed. It should be easy to add, though. After all, the AI can show what it is thinking, and this could be added to a file within the source code. It should not be too difficult to put all this into a /changes folder in the source as JSON files with a timestamp.
The user could always delete these changes again or disable them in the settings. But for me it would be such a useful feature.
