NEI and WAILA can help out a ton when doing liquid amounts. Furthermore, there are machine upgrades that can make them more efficient, so you need less liquid to do the same task, which complicates things even more.You've asked for it, and now it's finally here... Mekanism support is now available! There is one important caveat... I can't figure out the exact quantities of all the various liquid-based recipes, so the numbers have been completely omitted for that part and probably are a bit incorrect. If you have any further information about those recipes, please let me know!
help me automate crafting just like ae1 used to do
Well... first thing, did you overlook the "Craft" section of the website? That allows you to choose an item (or multiple items) and it will give you the step-by-step instructions of how to make everything along with a complete list of raw materials. It's actually a bit more powerful than the AE2 system since it already has all the recipes (unlike AE2 where you needed to make patterns manually).
If you want the data, the whole project is open source. You can find the recipe information in a YAML-like format on GitHub.
