Trello Horizontal Scroll

this does horizontal great, but then introduces vertical scrolling problem.... but it appears trello integrated it by HOLDING SHIFT circa ~2017 i'm guessing from this video. cool. https://www.youtube.com/watch?v=og9pZSC7tEU

Works as intended, but it disables vertical scroll when the extension is enabled, which kind of creates a problem where there was none before.

Vertical scroll disabled. Scroll speed in options is never remembered. I'm sure it's possible to yscroll when mouse over long list but xscroll otherwise.

For users without touchpad this is just a godsend. Option so intuitively expected that I can't get how one can work without this extension.
