Thanks! The github's auto complete for issue number is terrible.

Instead of adding a new signal, you could reuse node_configuration_warning_changed signal. It does update the whole tree, but it's connected to a Timer, so it shouldn't stall while writing the description, only once finished writing. Also only very big scenes would be really affected (thousands of nodes), so it's acceptable I think.

I'm a little worried about this as I prefer to not affect performance by this small commit. IMHO a little more code is fine compared to potential performance stalls, if we believe more and more people will use godot to make games with complex scenes. And it's not a configuration warning, so I think a seperate signal is fine. Feel free to correct me.

You should add some delay for updating the tooltip, otherwise it's changed with every written character.

IMHO the best way is to update the tooltip when the user left the input box (when it loses focus).

Also how do we do this, use a timer, and when user input something new but the timer is not triggered, we reset the timer?

Yes, the timer should be restarted with each input.

The timer should be in SceneTreeEditor, not Node.

[jsjtxietian]

Yes node is the wrong place (especiall when we dont have a editor macro) , but I wonder whether we should use a timer, seems a bit excessive

[KoBeWi]

The implementation looks alright overall, but I'd look into changing Timer to SceneTreeTimer. Though technically the PR works correctly and this can be done later.
