[Feature]: space as toggle the active row as to be "selected" e.g. for bulk cleanup #484

Problem

I'd like to bulk cleanup worktrees with their branches.

Proposed solution

For other tui tools I've made e.g. gh-pr-lander I build bulk actions from the beginning.
That makes me used to press a key (like space) to toggle selection and apply eventually an action to it. Here it would be select several worktrees and press d for deletion then.

Alternatives considered

I see that space is bound already, but I'm suggesting an alternative key for the layout toggle, because: muscle memory.

But of course open for suggestions of other keys to do the toggle.
