@lunareclipse@jeder Tbh they all should be stored as regexes, And they should just create a wizard (or a witch ;)) that creates the required filter line based on what you want to filter
Fe. You want to filter Gun So you put that in to the creator, you tick the box caseinsensitive, full-words-only And bam - you have it added to your filters. If you want to do something more fancy with regexes you can just edit them directly - but that way you don't have to bother with escaping symbols etc.
