The idea is:
Currently, when a core node is upgraded a little info box pops up in pre-existing versions of the node New node version available: get the latest version with added features from the nodes panel.
I think it would be very helpful to have an option/button somewhere in the node itself to auto-update to the latest version.
My use case:
My specific use case is the MySQL node, which I’ve used frequently. Having to create new nodes to replace outdated ones and copy/paste queries, etc to get the latest features is a drag and it would make things much easier if I could just update the pre-existing nodes.
