Trello Horizontal Scroll Extension

Trello by default doesn't gives the feature to scroll board horizontally whereas as the number of lists grows its not easy to view all lists by clicking and moving the board or moving the horizontal bar manually (surely this flow doesn't seems smooth on desktop and laptops right).

So, this extension adds the feature and enables the horizontal scroll on Trello boards.

Change Log:

v3.1.0
- Updated Options UI as per chrome extension's options UI version 2
with this update - now options window to set scroll speed opens up in extension page.

v3.0.0
- Provided option to customize scroll speed ( defaults to 30 )

v2.0.0:
- Fixed bugs: now horizontal scroll deactivates automatically once it detects the presence of vertical scroll bar within lists or cards.

Note: If horizontal scroll stops working while switching boards - please refresh page.

Ian Nastajus (ID: 000000e8ea3f035e) Voted 5 ★ - Updated 08/21/2021 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

icon

Flávio Lima (ID: 0000005c0f4ced55) Voted 4 ★ - Updated 05/15/2018 Works as intended, but it disables vertical scroll when the extension is enabled, which kind of creates a problem where there was none before.

icon

Robert Bancroft (ID: 000000996ab065c5) Voted 2 ★ - Updated 02/03/2017 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.

Den Drobiazko (ID: 000000928bc94cf7) Voted 5 ★ - Updated 06/30/2015 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.
