Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
This is intended to replace the icon on the header of each of the nodes, which is used to indicate which node to show in the spreadsheet editor.
Initial requirements:
--
Note: That also means that "Viewer Node" may need to be an explicit option in the spreadsheet. We can still keep the syncing happening though (in this case would simply change the spreadsheets to "Viewer Node").

Is a viewer node functionally different from the toggle on each node? in addition to being represented in the spreadsheet I thought it was supposed to enable an overlay of the node's output over the final derived geometry in the viewport? or did I read that incorrectly?
Pardon me if I should have written this on devtalk instead
Added subscriber: @HooglyBoogly
Yes, adding a viewport overlay is the next step, the current patch just shows the data in the spreadsheet though.
Alright. Has it been decided whether or not to decouple the node that gets inspected in the spreadsheet from the node that gets "visualized" in the viewport ? I'm asking this because a "node toggle" like what's in 2.93 seems more straightforward than a full-on node "viewer node". Even further, maybe just make the overlay show the active node output? That's what we really want to see when we tweak properties on a node : its output in particular. Every extra step in a process that involves a lot of "node inspecting" is going to be a burden, I'd encourage you to simplify the process to the max.

Re-opening since we should have them open until the next product demo.

Hello, I dont know if it's fine for me to post here, but here goes:
In the last Blender 3.0 Alpha there is indeed the viewer node and the Ctrl shift click shortcut sends the geometry form the selected node to the viewer node but nothing changes in the 3d viewport. Where am I supposed to see the node result the viewer is supposed to show?
Thanks
This is a Feature that isnt there yet. You can only see your Viewer Data in the Spreadcheet currently. Hope the Viewport visibility comes in 3.0
Then why has Node wrangler's Ctrl shift click shortcut changed? It went from taking you to the geometry output, to taking you to this viewer node that, at the moment, shows you nothing.
Added subscriber: @Erindale
Agreed. I'm not sure the viewer node is really helping much and it doesn't make a lot of sense to have it use the ctrl+shift+lmb shortcut when that's always used for connecting to the output in shaders.

Hey, not sure if its right place to post, but in Blender 3.0.0 2021-09-12 the viewer node doesn't seem to work inside the group at all. and it's quite buggy in the root. Whilst here, removal of spreadsheet button shortcut from nodes it's not a good idea IMHO. The UX now is so much worse, the viewer gets in the way too much, when juggling with nodes, Another issue is, that I can't easily tell what node I am viewing in the spreadsheet, it''s just show "Viewer", and it's hard to tell which node the viewer is connected to with bigger networks. With the old button I could easily tell via the button highlight. Please reconsider adding the button back.
