Channel rebalancing in lightning is interesting. I find myself literally drawing diagrams with colored pens to figure out how to move balances around. It's not exactly unintuitive, but you need to get familiar with how it works.
Also interesting I am seeing 0.1% fees for certain cases I'm looking at. I think rates will go down (even, drastically) from this over time, except for very large amounts.
(many know but: percentage fees *do* make sense here, unlike main chain.)
