When a flow is locked, then you cannot modify nor move any node. This is good.
But sometimes I need to check the content of a node. This is not possible.
I need to:
Unlock the flow
check the content of node I am interested in
Lock the flow again
Could we get the possiblity to view the content of locked nodes?
It does seem reasonable to allow you to open a node's config read-only. I don't know how easy it would be to implement though.
Incidentally you can see the popup if a node's config contains a description, even on a locked flow. Not at flow level though, tabs don't display the "I have documentation" flag.
You can also select a node or nodes on a locked flow and copy to another tab, which will not be locked. (!)
