Sorry in advance if this has been answered already. But I searched and couldn't find it
I have two Linux based systems: a live RPI Rasbian one and a development Lubuntu one.
When I deploy my latest development system I export all nodes to a text file from the dev system. Then on the live system I have to manually delete all tabs on screen and also in the layout before importing as a new flow the dev text file.
Am I missing something? Is there an easy way to zero your node-red system before importing? Otherwise I get double the tabs.
