I don’t know if I’m the only one, but when I used ditto I turned off the auto cleanup stuff. Basically I had it keep everything. I’d go cleanup manually every now and then (especially images), but having a very long term way to look up past code snippets was invaluable.

So then when I got my first Mac I felt lost without a clipboard manager with unlimited storage. I finally found Copy’em and my life has been complete again. :)

I haven't used ditto myself, but pastepal seems like what you want
