 # Node Design
 Now that we can do all the cool things ex. presets and such, it's time to think more design.
 
-## Categories
+## Nodes
 **NOTE**: Throughout, when an object can be selected (ex. for GeoNodes structure to affect), a button should be available to generate a new object for the occasion.
 
 **NOTE**: Throughout, all nodes that output floats/vectors should have a sympy dimension. Any node that takes floats/vectors should either have a pre-defined unit (exposed as a string in the node UI), or a selectable unit (ex. for value inputs).

+- Crystal

-TriMesh should support:
+When it comes to geometry, we do need to make sure
-- EnumProperty defining whether to select an object or a collection.
-- Medium
 
+### Notes
 **NOTE**: When several geometries assigned to the same medium are assigned to the same `tidy3d.GeometryGroup`, there can apparently be "significant performance enhancement"s (<https://docs.flexcompute.com/projects/tidy3d/en/latest/_autosummary/tidy3d.GeometryGroup.html#tidy3d.GeometryGroup>).
 - We can and should, in the Simulation builder (or just the structure concatenator), batch together structures with the same Medium.
