For a little while now, I have found that Clusters are not really usable anymore in Grasshopper2. Creating one is ok, but as soon as one try to edit it, the whole canvas becomes very VERY slow and laggy. Closing cluster to go back to parent file is kind of possible, but cluster editor is really closed only after a while.
Regarding Clusters, it would also be nice to have a visual indication we’re inside one : the blue background of GH1 was quite effective in that sense.
I totally agree, and I’ve noticed the same thing!
