Improved List Handling/Functionality

I often find myself needing to do certain things on list members such as removing or extracting the first/last element, or extracting/removing the nth elementh, reversing the list, etc. It would be great to have a transformer that allows these types of operations so you can manipulate list data easily (spoken by someone that doesn't do Python for a living!). I have also found one of @takashi's custom transformers (ListSampler) that is sometimes useful, but doesn't have the options I use most in the Sampler such as "Last Nth Element", which would be a great workaround to drop the last element in a list by picking the unsampled output. Thanks!
