Nice plugin idea, but…

This plugin will quickly use up all available memory if you have a large number of posts and a using a limited amount of memory such as what’s allocated on shared hosts. It does do what it’s supposed to and works great if you don’t have those issues to deal with. If one could get into setting a memory limit for it to use, it would likely work well for all setups, just be aware that it may have to swap memory with hardware, slowing it down a bit and possibly limiting the number of posts availabel to jump to at any given time.
