[Feature Request] Averaging a list of numbers

[ethanfischer]

I frequently finding myself wanting just get the average of a list of numbers. It would be nice if this plugin could do that.

For example, doing this:

00.6711065 00.6393984 00.6154768 00.6022926 00.5930304 00.5990342 00.6834856 00.6083402 00.5939903 00.6166123 00.6151632 00.6226189 00.6166091 00.6138560 00.6207100

average

Should put the average next to the word average
