Window Fit "Automatically Center on Cursor"

Windows OS version

Windows 11 24H2

ImageGlass version

v9.3.2.520

ImageGlass release

Classic

1️⃣ Describe the feature

• Currently, Window Fit mode is affected by your cursor placement.
• For example, if you use the scroll wheel to zoom and cause the ImageGlass window to become positioned outside of your cursor, additional scroll wheel inputs will not register.
• This is true regardless of "Automatically center the window in Window Fit mode."
• I propose an option that would cause ImageGlass to re-center on the user's cursor after each zoom tick.

2️⃣ How to use feature

In Settings > Viewer, replace the "Automatically center the window in Window Fit mode" checkbox with a "Window Fit mode center behavior" dropdown menu. Example values:

• Center window on monitor
• Center window on cursor
• Do not center

EDIT - you could also calculate the center of the ImageGlass window as a negative offset for the zoom. That might make more sense than using the cursor. Right now, it uses the top-left of the window as the origin.

3️⃣ Additional context

Short video that demonstrates why current UX is a bit cumbersome (I'm using scroll wheel throughout entire clip):

Thank you!

Start in Settings > Viewer and trace the Window Fit mode behavior while reproducing the issue with scroll-wheel zoom. Done means replacing the existing centering checkbox with a behavior choice covering monitor centering, cursor centering, and no centering, while preserving usable zoom interaction.
