I am in V8.
In footprint editor context menu - Renumber Pads.
You set first number, and step then click at first pad and move cursor through all pads - done.
Your animation shows something like KiCad’s Renumber Pads feature that Piotr mentioned. Currently this only works in the footprint editor for pads. It would be a reasonable feature request to add it to the symbol editor to work on pins, too.
And not only to the symbol editor but also to annotate symbols in the schematic or layout.
An option to number/annotate items sequentially according to the order in which they touch the selection box. Optionally support a single-click workflow (hover over or one click per item) for manual sequencing.
I prefer consistent workflows for similar tasks across the entire application.
That’s exactly what I meant, use annotate to create incremental references at schematic level by hovering over symbols. Just in the same fashion as one would hover over pins to increment pin numbers at the symbol or footprint editor.
