A minor thing: I set a break, then decided to make it a go slow rather than a complete break. Now the lines under "Upcoming changes" include:
Until 2017-06-15 increase at rate 2
Until 2017-06-15 continue at rate 0
From looking at the far right hand side of the chart, it looks like the 2 overrides the zero, but I still find this confusing. Would be nice if such lines could be removed.
