Warning message to the admin

Hi,

I am wondering if there is a way to achieve this: each time an admin drags a particular node from the palette to the flow area, he should be warned with a message (notification?), but not at every deploy. Only the first time he drags the node from the palette.

Is that feasible?

Thanks
Fabio

Have a look at the docs for custom nodes. I think there is a method that covers that use? The editor has the RED.notification function that lets you send a msg.
