Please move 'Open in.

Please move 'Open in...' gesture back to the main panel

The 'Open in...' button was recently moved from the main panel to the side panel, and seemingly only available in the 'Files' tab. This is one of the gestures I reach for most and now it's buried.

It was previously a split button with the most recent app as a button and other apps available in the dropdown, so this is also an extra click.

首先在 Windows 10 上的 /chat 路径中重现该行为，同时检查主面板和 Files 侧面板。当主面板再次提供“Open in...”时，恢复最近使用的应用分割按钮行为，并且不再需要额外的导航步骤时，此更改即完成。
