Hi, thanks for the feedback!
You can find my notes on things to do and ideas here:

There’s also the known issues on GitHub:

I think apart from fixing high-priority issues, next on my list would be getting the plugin code going on GitHub so it’s easier for others to contribute.
I don’t have any major new features planned. It would be nice to get the “field cloning” working, but I’m not sure when I’ll get time for that. Generally, the plugin’s been developed quite intensively over the past year, and I’m happy to ease the pace a little, fix bugs as they arise, and let it stabilize.
