I still have issues getting used to it, specially because the slicing preparation is soooo much longer and not at all what I'm used to. There is still a lot of bugs, performance issues etc.

But for the UM2+ I sadly need to use it. But the software has potential if they optimize it and fix bugs in the front end gui. I started having a look at the sources, but my time sadly is limited.

They have several new features I like, e.g. Different infill patterns, some experimentals like furry/fuzzy surface or grid surface.
