The current version 2.1 is quite stable and working nicely in most cases.
There's still need for tutorials, if anybody is working with the add-on, I will be glad to see some.
Next steps in development will be finishing exact silhouette algorithm, later doing better collisions generally, afterwards probably some path optimisations, like various options for entering material e.t.c. or completely new strategies.
Any form of feedback is welcome, I will respond as soon as I can.
