I have seen examples of clip-board managers in this forum and elsewhere too. However, I am not sure, if they offer a facility to save the source of the clip as well. For example, I may be reading a PDF file, a web page, code in terminal, browse a diagram on some web page, etc. When I copy or take a screen-shot, I want my clip-board to save the information of the source as well. So that, I can easily refer back from where the clip was taken.
Would you know of such an application ?
