Repository navigation
Chart navigation. Pinch on the trackpad or use the mouse wheel over the plot to zoom around the point under the cursor, from one minute up to the automatic view; the point stays where it is while you zoom. Scroll sideways with two fingers, or drag the plot, to move back and forth in time, never beyond the recorded history. When "now" leaves the view a chevron at the right edge brings it back, and one at the left edge jumps to the start of the history, both keeping the current zoom; they highlight on hover. Reset, or a double-click on the plot, returns to the automatic view; zooming back out to it does the same. Jumps and Reset glide to their destination. A zoomed view whose right edge "now" reaches starts following it, as the automatic view does.
Axis and readings. Time labels run from the start of the view on the left to "Now" on the right, evenly spread, never closer than a minute and with seconds for views under two minutes; labels step aside from the hovered time. Hover readings always refer to a point inside the view.
Panel. The activity log starts collapsed in both the popover and the window, and both the chart and the log remember how you last left them.
