I use fire display most of the time, temperature display some of the time, pressure display rarely, and nothing else.

I use fire,heat and pressure display.

I use
1) Fancy (or Fire)
2) Pressure
3) Temperature
Almost nothing else

I use velocity when building something and fire/blob/fancy to view it, because it looks pretty
I only use pressure or heat to fix some problems involving those two. Persistent is completely useless to me, but oh well...

now fancy would be like in 2 or third spot for mee

I am not using velocity view because i don't understand it
I use pressure instad of this

Nothing view

I used to use fancy. but I realized fire is fancier :P
You guys gotta fix the glowing metals on fancy view.
Anyways, I like fancy stuff. Tough I choose usually what I'm working. If I'm working on a heater, I pick heat view. If it's some kind of pressure thing velocity fits(It's easy to understand for me). When I'm working on a nuke, I view both.
