Icon View, Auto-Insert Feedback Node, Auto-Tool, Scripting.
The default settings I change on each install of LabVIEW. I'm not saying my views on these features won't change, but I do think that it tells you something about what kind of LabVIEW programmer you are if you only ever use the icon view for terminals.
I believe there was a CLAD question once that was something of "What are the main components of a subVI". Likely wanting you to say Block Diagram, Front Panel, but I agree that a VI doesn't really need a front panel. And if I choose to remove the block diagram I guess my VI doesn't really need that either.
But at some point I feel like we may lose something. LabVIEW is visual (duh) and as a result I feel like my brain makes connections between the subVI icon and the functions it performs. This helps me remember things very quickly and traversing down the rabbit hole of subVIs seems easy because i remember all their functions visually.
Likewise my brain makes connections between the front panel and block diagram and knows how controls on the front panel and indicators are coupled. I started this post wanted to say I was on board with removing the front panel, but now I'm not so sure, unless there is again some visual way for me to understand code in a way that is hard to explain. In text based code I find my self remembering what the code does, based on the shape of the text in that line (or surrounding lines). I feel like I'm a better programmer because of these visual connections, and I hope that if the Front Panel goes away, some new method will be there to replace the visual connection that will be lost.
