I made a filter with a randomizer to find your boyfriend. Now I want to make the exact same effect but to find your girlfriend. Is there a way to duplicate the effect and edit it?
Are you referring to using that effect/project as a template? If so, in the project that you want to duplicate, try clicking “Save As” and typing in a new project name. It should then show up as two different project files on your computer. Another way you could try would also be to copy, paste, and rename the same effect file on your computer, but I think Save As would be the easiest way to create a duplicate.
To duplicate a project as mentioned by @haleycatpawz the easiest thing is to save it. When you reopen it, you edit it and change the name.
