I wanted to make a list of things that will improve, but I will PM you the list when it's complete.
There's one thing that I would like to mention here cause it's most important:
I know the batch submit doesn't work now, even if it's available, but it will be really nice if you can use something like {name} in the description, or {words} in the tags field, and it will know that "name" means auto-complete with the torrent name, and "words" will just split the torrent name in every possible combination and submit that as tags.
Just an idea that will be very easy to code.
