New setting for minnows to see all amounts with three decimal places:

Yes! I love this feature! The two decimal places and all the rounding have tripped me up for a long time. Soon after I joined Steemit, when STEEM and SBD were worth more, I had checked Steemnow's upvote calculator to know how much SP would be needed to be able to give a 0.01 upvote, and the calculator started showing 0.01 around 25 SP. But it turned out 25 SP only gave a 0.005 upvote, and Steemit, Busy, Steemnow and every other interface rounded the number up and displayed it as 0.01. So, 25 SP only gave half of what the number showed!

The same kind of thing happens when people try to give an upvote so that a post or comment's rewards can get above the dust threshold of 0.02 (rewards below this value don't pay out), but the UIs keep rounding numbers from 1.015 to 1.019 and displaying them as 0.02. This leads people to think they're handing out 0.02 upvotes when in fact the votes are in the range of 0.015 to 0.019. If the post or comment doesn't get any more upvotes (more common for comments because they don't get as much visibility and as many upvotes as posts), the rewards just won't pay out at all and the votes will simply be wasted.

A 0.005 value may not mean much to bigger users, but for minnows and plankton it makes a huge difference. Thank you for implementing this feature! Now the rounding up shouldn't deceive us anymore.
