**Short description of error**
[https://pythonrepo.com/repo/Pullusb-viewport_timeline_scrub This appears to be added to the Grease Pencil Tools Addon. The problem is, if someone is using the Industry Compatibility setting under Keymap, this addon overrides the Alt MMB to navigate.
Maybe add a switch to Turn this OFF on the Grease Pencil Tools Addon? ]
**Exact steps for others to reproduce the error**
[Turn on Grease Pencil Tools Addon
Set the Keymap to Industry Compatibility
Try to Pan the camera, you get the Timeline Scrub.
When I turn OFF Grease Pencil Tools Addon, the MMB works]
[Based on the default startup or an attached .blend file (as simple as possible)]
