System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.11

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-09-12 09:51, hash: b5a1c194c5
Worked: unknown if it ever

Short description of error
I might be wrong here but I was under the impression that we're now able to create a mesh instance and be able to modify it with geometry nodes, without a mesh to modify preexisting, out of 'nothing' so to speak.
If I delete the default cube to have an empty project I can't add any nodes to i.e. instance a mesh and take it from there. Without a mesh the "+New" button above the node grid doesn't work. Nor do any of the options in the "Add" menu.

Exact steps for others to reproduce the error

open new general project
delete default cube
switch to geometry nodes workspace
check nodegrid workspace "+New" button and workspace menu entries for usability (ie Add) - all choices should be disabled so

If I delete the default cube to have an meshless project I can't add any nodes with the workspace menus to instance a mesh and take it from there. Without a mesh pre-existing (ie default cube) the "+New" button above the node grid doesn't work, nor do any of the options in the "Add" menu that could potentially instance a mesh out of nothing but nodes and store the node tree within its instance (and possibly a resulting new mesh line in the outliner for the instance), no?

Thanks for the report. Geometry nodes is a modifier used to change the geometry of the Mesh and curve with the help of nodes.

So without an object in viewport, it is not possible to add a GN modifier. (this make sense for me)

This is not a bug so I am closing this report. But feel free to reopen if this is just misunderstanding from my side.
