I think if I want to solve a problem, intellisense already became a requirement for me, since it does increase speed and I would say that this helps "fluidity".
I see some other side effects though and that regards labeling. I spend much less time on thinking about fitting ones since they would be auto-completed on later use anyway. If I don't have intellisense available I spend more time on thinking about names just because I need to remember them. That makes the code much more readable in some cases.
Exploring APIs can be much more enjoyable if you have it and there is no thorough documentation available on the other hand.
Still, some projects have a lot of constants and variables, so in that case it really helps.
