Also, a way to separates the blocks of activities something like the flowchart on UiPath. If you need some help to develop features here's my Twitter also my GitHub account, always happy to collaborate.
I have a workaround, create a conditional STEP, drag the step you want to disable into the false part of the condition so you don't lose the step, and that step doesn't get run when the flow runs.
Its a bit odd that something so many have desired for so long is not available as DISABLE or ENABLE. I support the need for this functionality vs a workaround to "save" the flows value.
We are now working on this feature.
