Agital

Percentage change figures that Google Search Console leaves out are what Agital adds, as a Chrome extension named GSC Calculations. It calculates and shows changes for clicks, impressions, click-through rate and position, and it overlays Google algorithm updates on the timeline graphs so you can see context for performance swings. It works inside Search Console itself and speeds up organic traffic reporting. It is meant for SEOs who compare periods regularly and want instant calculations rather than doing the math by hand.
