We now have Variable or Auto Header Height (thanks to @jahanbakhsh18) which is a great addition to the previously released Variable Row Height. Also included in this release are: new multi-range selections, column resize auto-scroll and column reorder auto-scroll and a bunch of other features and fixes.

See all new examples
