Right click a NanoFlow and choose convert to Microflow.
When using a nanoflow at a certain point in time you need to add functionality and and a nanoflow isn't sufficiant anymore.
It would be great to have a option to convert the nanoflow in 1 single click into a Microflow.
Thank you for the idea, this could be a nice delighter. Please note that currently you can copy/paste between nanoflows and microflows. Therefore it is not planned on the short term because we want to improve first on other areas for nanoflows.
