Quick persistent scratch buffers | Umar Ahmad

Emacs has a feature where you can quickly open a buffer to paste or keep text temporarily. It can be done by calling switch-to-buffer and typing out any name and pressing return. If a buffer with such a name exists it shows up, otherwise an empty buffer with no associated file is created. I discovered this accidentally years ago and have been using this feature a lot since.
The problem with this is that the buffers created only last till your emacs session lasts.
