Zoom with Middle Click Drag

Problem

Navigating with pen tablet is inconvenient.

How it Works

Zooming works usually by pressing + - and scrolling with mouse. Zooming with mouse scrolling is smooth and focused to pointer as expected but not achievable with pen tablet control. While zooming with keyboard shortcut is choppy and doesn't navigate to pointer which is quite hard because user needs to pan around to a desired view. There's also a feature to zoom to area with shift + middle click drag but it's not common in other software and it's not possible to zoom out with that.

User that used to work with digital painting and 3D programs expects to have a feature to zoom, pan, and rotate with middle click. (usually available on their pen)

Right now middle click control only works with panning and rotation.

How to Fix

Provide control for smooth zooming (like Ctrl + Scroll) with Ctrl or Shift + Middle click Drag. The navigation for pen tablet user could be something like this:

• Ctrl + Middle Click Drag to Zoom
• Shift + Middle Click Drag to Rotate
• Middle Click Drag to Pan around

How Other Software Handle

Adobe Illustrator: from what I know doesn't support this by default. Needs a little workaround.

Krita:

• Ctrl + Middle Click Drag to Zoom
• Shift + Middle Click Drag to Rotate
• Middle Click Drag to Pan around

Blender:

• Ctrl + Middle Click Drag to Zoom
• Shift + Middle Click Drag to Pan
• Middle Click Drag to Rotate
