In light of all my recent problems and seeing a new NR is soon to be released, I thought about the layout.
At first I didn't get the idea of having different "tabs" on a machine. But then, when my flows became monsters I appreciated the separation of different parts of the flows/code.
(See attached for a better explanation of what I mean.)
Although maybe not often used, they can be a pain if/when you have a lot of them.
A drop down list would be a nice alternative.
And/or maybe a name search, so if you are looking for a tab of name x, you can search for it rather than having to scroll - for the existing scenario.
Only a suggestion.
