As many designers, I sometimes find myself designing elements not for a particular project but only because inspiration was there and I might use it in a later project. It could be a button, an icon, a character or whatever.
When they are finished, I used to just through them inside a folder, which I would reorganise later when I have time. But as their number is growing it becomes more and more difficult to find what I'm looking for.
I think this could be fixed by abandonning folders introducing some tagging system with a search feature, but I would like to hear some thoughts from other designers.
How do you organise and sort you work to be able to retrieve it later efficiently? What software do you use?
