Topic filter- 'Topics I Haven't Replied In'?

[catnet 9,357]

I couldn't see something like this having been suggested before (if it has and I've missed it, I apologise), and I'm not sure how difficult or time-consuming this would be to introduce, but I've been thinking about it, and I guess it's worth mentioning at least.

 

 

Along with the current custom filters, I'm wondering if another filter under 'Show topic type'- Topics I Haven't Replied In- could be a good addition. I can imagine something like this being useful for members that have posted in a lot of topics already and want to quickly find more topics they've yet to contribute to... otherwise it could get boring looking through many pages and seeing loads of topics they've already finished with or have little else to say in anymore. x3
