It is just a port of the original plugin to 1.16(the old version does not work anymore). It was never designed to invent a new concept.
I'm probably going to add configurable messages for the 1.0 Release, but it is just a plugin for builders, and they should be fine with the current messages. This plugin is not designed for normal player interactions.
Great plugin, Im glad you updated it to the 1.16! However it would be very cool if you could add some additional "blocks" to the GUI, all of the 1.16 stuff would be great of course but also netherwart, all the other flowers and the whole ocean stuff.
Another cool feature would be a /cf list command which lists all of the saved "flowers". An addition to that would be a button in the GUI which leads to another GUI where the saved flowers are listed.
Thanks for your Feedback.
I will implement that later especially because FAWE is still not marked as stable and I currently have many other Projects in development.
The Code is open source so feel free to implement it yourself. ^^
