feat: Double-click to move tasks between Backlog and Sprint

[RSnew]

Problem

Currently, moving a task from Backlog to Sprint requires drag-and-drop. This is cumbersome, especially on smaller screens or when working quickly.

Proposal

Double-click a task to toggle it between Backlog and the current Sprint:

• Task in Backlog → double-click → moves to active Sprint
• Task in Sprint → double-click → moves back to Backlog

This is a very common UX pattern in task boards (e.g. Things app, Linear quick-add).

Alternative

• Keyboard shortcut (e.g. Enter or Space to move selected task)
• Right-click context menu with "Move to Sprint" / "Move to Backlog"

Why

Makes the board feel snappier. AI agents also benefit from simpler interactions — fewer DOM events to trigger programmatically.

Hi @RSnew

Thanks so much for the contribution and for opening this PR! We love seeing community ideas to make the board snappier.

I'm a bit worried that a double-click toggle might confuse users with accidental moves. Also, for smaller screens, users can currently use the sidebar to move tasks to the sprint.

We actually plan to support your keyboard shortcut alternative in the future!

[RSnew]

🤔hmm，maybe this needs a new trigger instead?

[pikann]

Yeah, exactly! What if we trigger it by hovering over the task and pressing a key?

• S: Move to active Sprint
• B: Move back to Backlog

This avoids accidental double-clicks and makes it super fast on small screens without needing to click or drag. What do you think?

[RSnew]

maybe add a small inline “Send to sprint / Backlog” button on the card (with a matching keyboard shortcut)？
That gives a very explicit trigger and is harder to hit by accident than double‑click.

[RSnew]

Maybe on mobile we could also support swiping left/right on a task, kind of like in iMessage.

[pikann]

I love that idea!

Since adding an inline button might make the card look a bit cramped on smaller screens, how about we use a "More options" (3-dots) button on the right side of the card, or a right-click context menu?

The menu could include "Send to Sprint" / "Move to Backlog" and explicitly show the matching keyboard shortcut next to the text (e.g., S or B). This keeps the UI super clean while giving users all three ways to interact (Mouse, Shortcut, and Mobile-friendly tap)

What do you think about it?

[RSnew]

that sounds really great! I’m really enjoying this discussion🥳

Feel free to update the PR whenever you can! Or, if you're busy, just let me know and I'd be happy to take over and help get it merged. 😊
