Not sure if this counts as a bug, but shouldn’t the my.sketchup paint bucket have a dropper for sampling colors? That’s pretty important.
Not a bug, because the web app is in beta, and many features are not yet implemented.
Not a bug yet, because …
But will, in my opinion, be a bug if not implemented when my.sketchup (non-beta) is official.
We haven’t completed my.SketchUp’s implementation of SketchUp’s materials system, but recognize how important it is to have a more complete set of features there. Including being able to use the eyedropper to sample materials from the model.
