[Feature]: Let User Navigate With One Finger When Pen Mode Active
### What's the feature?

Feature Request: Enable one-finger navigation/panning when the pen mode is active.

Currently, users need to use two fingers to navigate, which is typically associated with zooming, or they must switch tools—both of which disrupt workflow efficiency. Enabling single-finger panning, especially on mobile devices, would streamline the user experience, allowing for smoother, more intuitive navigation without interrupting the drawing process. This feature would greatly enhance usability and workflow fluidity.
