Hi Claire,
Actually I’m quite happy with the way of working described above 
. The only things that are still missing right now are receiving Attribute User Text back in Rhino and less importantly, line styles and annotations don’t work at the moment, so actually the way of working I described doesn’t quite work yet. But I thought it wasn’t necessary to mention that, because I know you’re working on it and will release it soon. Looking forward to this! 
The GH receiver node looks very nice! 
When FE2, together with the new URL structure, got released I found it harded to understand what model was being loaded when looking at a GH script, but this new receiver component looks like it solves this issue.
Regarding working with objects, I’d say that it should be possible to construct and desconstruct Speckle Objects directly from these new Rhino Model Objects. Although I have a hunch for what some of the reasons will be, the question that comes to my mind is:
Why do you create a Create Speckle Property Group component, instead of making people create this type of data with the native components?
Like this:
RhinoObj-SpeckleObj-RhinoObj.gh (12.5 KB)
Now it doesn’t work yet ofc.
The Search… component looks interesting as well. Eager to learn more about that
