Yes, it does take some getting used to. I was in the same situation as you when I first started using it. Then it eventually started to click and now I use it quite frequently - mostly for recipe design and recipe tracking. I really like the way it lets me tweak recipes so I can save previous versions of a recipe in case the newly tweaked recipe doesn't work out. For example, I'll save v1, v2, v3 of a recipe until I get it just how I like it.
I also use the various tools like hydrometer adjustment, alcohol-percentages, attenuation, etc.
