Problem Statement

Currently in the Claude Code VS Code extension, I need to hold the Shift key while dragging files into the chat input to attach them. This adds unnecessary friction to my workflow, especially when I'm frequently referencing files during development. It would be more intuitive if I could simply drag and drop files directly into the chat input without any modifier key, similar to how most chat applications and IDEs handle file attachments.

Proposed Solution

Make plain drag-and-drop (without Shift) the default behavior for attaching files to the Claude Code chat input. When a user drags a file from the VS Code explorer or editor tabs into the chat input area, it should automatically attach the file as context — no modifier key required. If a modifier key is needed for an alternate behavior (e.g., inserting the file path as text), that could use Shift instead.
