I'm trying to understand the discussion so far, but I think I'm lost. I can't seem to find regular expression matching or simple string matching e.g. "~some file.pptx".startswith("~") in the Alfred settings. Is it true that Alfred does not and will not allow users to exclude items from the result by using string matching or regular expressions? For example, I never want to see the Microsoft Powerpoint backup files that always start with the "~" character. However, I do want to see the actual ".pptx" files. I would like to tell Alfred that I don't want to see results that match this regex: ^~
