Since Blender 2.5 I'd say the interface has become rather intuitive. I watched one tutorial from Blender Guru and was already making stuff. I mean the keyboard shortcuts are obvious too, 'G', 'R', 'S' for Grab, Rotate and Scale. 'X','Y','Z', to constraint the transformation to the corresponding axis, however from what I gather from previous posts here is that wouldn't matter because the interface would be entirely editable.
TBH though, this seems to benefit only Blender users giving them the features of Blender for use with Leadwerks, since it seems to be a plugin for Blender? Therefore only really helping out the minority of people here which means Josh's time could be best spent working on some other part of the engine.
