I still work on many things that were still not intuitive or buggy. I think its pretty save to use already.
- Added the AdvancedParticleVisualizer for API users, that allows way more shapes and types of effects
- Made Datastorage less dependent on main code
- Removed all AnvilGUIs to make the plugin less protocol dependent
- Introduced `/node edit <nodes> addgroup <group>`
- Introduced `/node edit <nodes> removegroup <group>`
- Introduced `/node edit <nodes> cleargroups`
- Changed the editmode to only use 6 slots.
- Changed last group in editmode to multigroup tool, which allows to add and remove multiple groups at once
