VS Code extension: auto-open/pin the file Claude is reading or editing in a side editor group

When using Claude Code inside the VS Code extension, I'd like the file Claude is currently reading/editing to automatically open in a split editor group next to the chat, so I can watch it update in real time as Claude works.

Today this requires a manual routine at the start of every session: click the file (from a Read/Edit tool-call entry or the Explorer) to open it as a tab, then manually drag it into a split (or use the split-editor shortcut). I tried setting claudeCode.preferredLocation to "sidebar" hoping it would free up the main editor area for files to open automatically, but Read/Edit tool calls still don't open the target file as an editor tab at all — it has to be opened manually every time.

Request: an option (or default behavior) to automatically open the file currently being read/edited in the adjacent editor group, and ideally remember that split layout across sessions in the same workspace, so this doesn't need to be redone manually every session.
