Find days with no entry

[carygravel]

Is your feature request related to a problem? Please describe. The statistics window show the proportion of days with entries. I'd like to locate those days without entries, without having to click through years of them.

Describe the solution you'd like Maybe arrows next to the forward and back buttons. Or a different mode for the forward and back buttons, so that they skip to the next empty day, rather than non-empty day.

Describe alternatives you've considered
