v0.10.0

I have been writing tutorials for the past few weeks and have finally finished the basic parts.
This version includes scenes that can be used as templates, so I hope it's easier for more people to try this plugin.
If you find any errors in the tutorial, I would appreciate it if you could let me know.

I also have found several bugs and difficulties in using the plugin, which are fixed in this version.
