When importing a flow and there are duplicate nodes, the window cannot be resized making it impossible to view the complete name (MacOS 15.6.1, Safari, Node-RED v 4.0.9). Also, the icon next to the name is barely visible (if it is not selected to be imported).
Also, when importing a copy of the node(s), is it possible to append the word “copy” to the node name? That way it becomes easy to see which are the copies and either rename them or delete them.
