Current status/Todo list

[ethindp]

Here is what we have so far and what needs to be done. Contributions appreciated! Feel free to jump right in and start development of anything on this list -- there's lots to do!

Dependencies are marked in parentheses alongside each todo item, if any. The majority of these tasks depend on a number of issues that need to be closed first, so not all of these can be done in parallel.
