I recently discovered it was possible to set a custom AI prompt on a per feed basis which is a great feature. However I couldn't find a way of changing the default prompt - I think this would be really useful to be able to configure this. Even better would be the ability to manage and save multiple different prompts and be able to select one at the time of use. Maybe you could have a "default" prompt which is used if you just press the AI button but if you long press it you can choose a different prompt from a prompt library instead.
