I was re-importing a flow via clipboard and ended up with this dialog
and I found it confusing - nothing new there
Just referring to my win8 node (which is MQTT config) I eventually realised that I had to tick the box on the left to copy it but that if I wanted to replace existing with it - I had to tick the one on the left and the one on the right
I feel it would be clearer if there was one dropdown (or something like that) with ignore/copy/replace
type options for each item
