I made a bit of an update.

You can now configure how many decimal points to show.
For now, I'm just truncating (rounding down) the number instead of rounding normally. I figure people might prefer this so they can see when price milestones are actually passed. So you can set it to 0 decimals and see when each new dollar point is actually reached, instead of just when it gets rounded to the next dollar.

You can also disable the label next to the price, or change it to the ฿ symbol.
