Allow me to toss a hand grenade. As a baby step toward that end I suggest (I am being serious) that you turn on icon view for terminals and use it. Keep an open mind and try to make it look good.
Wire bends? Yes there will be more on average, but they are longer which is easier to follow and much less annoying IMO than those 1 and 2 px jumps.
They take up more space? Yes! This has two benefits. It drives down the density of your BD, and triggers that urge to create a subVI earlier. Helps curb mission creep inside a VI. Second benefit: lower density leaves more "slack" on the BD for when you really need to add something. Tight-packing means that adding a single node can literally affect every other node on the diagram.
Perhaps that tall stack of terminals can become a type-def cluster.
Bonus: NI insists on resetting this setting with each release of LV, just sit back and enjoy it instead of cursing every time.
Now, once you have accepted the joys of less dense, more focused subVIs, it is easy to move from icon view to control view.
The more focused subVIs are easier to test, maintain, and are much likely to be reusable. Every node you add tends to increase the specialization.
