Hi there @fpwong ,
The plugin does not format the best in Behaviour Tree.
Step 1 - add nodes and format - https://i.imgur.com/4Lj8aUD.png
Step 2 - move nodes around - https://i.imgur.com/LvgyJse.png
Step 3 - format - https://i.imgur.com/tdnpjB2.png
I think that opening and closing BP tree fixes it, but that is not really a fix 
.
I am also looking forward to Praxinos fix since I would like to use it in my project.
Thanks!
I love the plugin so far!
