Brush Picker Tool and Brush Organizer in Photoshop

A problem I have all the time:

I am searching for hours to find the perfect brush to paint or draw something in Photoshop. But when I come back to the project a few days later, it is almost impossible to find out which brush I used (unless I renamed it somehow, but with a lot of projects you quickly loose track and it gets a bit ridiculous).

Also while working, only by clicking a few other brushes to try out something, you loose your brush super quickly due to the very limited "brush history bar". It becomes especially annoying, when working on different projects at the same time, going back and forth, because the brush history ist not linked to specific projects.

Ideas:

- The possibility to use the picker tool on illustrations (etc) to find out which brush was used (please!)

- A better way to organize and "remember" brushes as favourites or in project files for later. 

- The used brushes are linked to the specific project file you are working on.
