I wasn't sure whether i should create this in suggestions or xenforo discussions as it's more for to apply on xenforo.com but then if it was applied and implemented here it would be in the core so I'll suggest it here. An option for users (like the ignore feature) to hide peoples signature on a per person basis. Atm the only way to block a signature on a per person basis is to block their account, this way users can block signatures without the need to resort to blocking accounts. Hopefully we can see this implemented at some point in the future. Keep up the great work.
