Changelog 0.5.0

Added

Comments in plots: text, freehand lines, shapes and arrows (press E or use the pen in the title bar; T, S, A pick a tool).
Show signal names next to their curves (press W)
New operation “Segment Metric”: one value per segment, e.g. per lap or cycle.
New operation “Concatenate Signals”: joins the points of several signals, e.g. one result per measurement into one curve. “Add same-named from other tabs” fills it (and Average of Signals) with every measurement in one click.

Signals with the same name in a tab are the same signal: editing one also updates its identical copies. Duplicate creates an independent copy with its own name.
The middle mouse button pans the plot
Recipes show which tab they copy from or paste into, and can be applied into a new tab per data source.
