Saved or recently used prompts quick access

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What problem are you experiencing?

When I want to use a previous prompt I had saved, I have to copy paste it in from a note node, which gets messy quick if I have a lot of prompts to switch between.

### When does this problem occur?

Whenever i want to modify multiple prompts but keep them all saved.

### How often do you encounter this problem?

Multiple times per day

### How much does this problem affect your workflow?

Minor annoyance

### Current workarounds

I just paste it into note nodes scattered around and copy paste it manually, moving text around to keep both the existing prompt and saved prompt intact.

### Ideas for solutions (Optional)

Maybe a button on the node for recently used and favourited prompts?
