You can of course rigidly memorze ranges and play by them. It's not that bad idea if you want to quickly fix some of the preflop leaks of yours and jump straight into the game.
The question is if you will really understand why the ranges look like that and how to apply them in real poker situations. I advise you to learn how to construct your own ranges. You will learn when to apply different types of ranges, calculate bluff-value ratios, how interconnected are ranges (for example 3bet and CC ranges) and what types of hands are good to include into ranges (for example 3bet bluffing ranges).

I think in learning steps there are videos about preflop ranges, also check newest Carroters video about types of 3bet ranges and check out his book Grinder's Manual - comprehensive info for 6max and there's a few chapters on the preflop ranges. I'm reading it for second time and can recommend it.

Snowie has its strengths and weaknesses. Using Snowie to improve preflop is a good idea but you should also make exploitative adjustments.

What´s up with the small blind limping strategy? Anyone does that?

Okay guys one more question:

Pokersnowie gives great advice for situations when there is only one raiser.
For example Snowie advices you to call 77 but not 66 against UTG open when Hero is on the BTN. But what if for example the CO calls. Does it make a difference?
Are there any solutions for that and if how can i get those?
