Sometimes I feel that I need to keep some notes about a folder. And its really inconvenient to keep that in a text file. And each time I need that information I have to open it and see it. But how it would be if I could stick the text with the folder so that I can see it right away when im inside the folder? I've attached a picture to make my point more clear.
Do you know any such software? or any trick that does this for me?

EDIT: Thanks to @Lamb and @JonathanReno both for nice answers. If I define the requirement by a sequence of activities, it will be like
- I will come inside a folder.
- I will Right Click > Click on Menu or Click any Button so that I can get a text box to edit.
- After writing I will save it.
- The text will be visible right away. Even anytime later I came in this folder, it will be remain visible.
So given this situation, I think @Lamb's approach is closer. Its just one step away to show me the text since i ve to select the file (readme) ;) And its not that big deal for the time being I think.
