Problem Statement

I accidentally clicked the delete button on a conversation in the Claude Code desktop app and permanently lost my chat history. There is no confirmation dialog before deleting, and no undo or restore option after the deletion happens.

Proposed Solution

1. Add a confirmation dialog when the delete button is clicked ("Are you sure you want to delete this conversation? This cannot be undone.")
2. Or add an "Undo" option that appears briefly after deletion
3. Or add a "Recently Deleted" section where conversations can be restored within a few days

Alternative Solutions

1. Add a confirmation dialog when the delete button is clicked ("Are you sure you want to delete this conversation? This cannot be undone.")
2. Or add an "Undo" option that appears briefly after deletion
3. Or add a "Recently Deleted" section where conversations can be restored within a few days
