Remove or increase pin limit for DMs

I love pinning funny or sweet messages with my friend and we very quickly ran out of pins, 50 just isn't anywhere near enough! I can understand having a pin limit for servers so it can be limited to important stuff, but a limit on DMs or group chats is totally unnecessary! I love to look back through the pinned messages and remember fun moments, and having to delete older pins or work around it some other way is just an unnecessary hassle.
