Thanks for the list, all three sounds like a pretty good feature to have!
Request 3 wasn’t skipped because it was too hard - we simply did not have the need to add it.
I added the requests to our issue list:
Unfortunately we have a few things going on which requires much of our attention, so I can’t really promise to do them in the near future (next few weeks).
I am sure we will get there eventually though.
Meanwhile both the issue tracker and the repository is public, and contributions are welcome.
