Combined with interpolation in the reference columns, it's now easier to see how live data compares with the plan for people who want that expressed in numbers instead of pictures. Last night's change adds a bit of visual distinction (for now just a yellow background, but it's trivial to change that to several other styling options) to the row containing the latest measurements so it's a bit easier to spot that at a glance.
There are a couple minor tweaks that I still want to make, but I think it's all stuff that I had in the last public release that should be trivial to port into the new code base when I have the time to look at that.
