WindowTransparency v1.1

Changelog: WindowTransparency v1.1

New Features

• Process-based transparency control
  The script now targets all windows of the currently active process, not just the focused window.
  → This ensures consistent transparency across multiple windows of the same application.

• New shortcut: CTRL + ALT + Middle Mouse Button
  Toggles "Always on Top" mode for the currently focused window.
  → Displays a tooltip (Fixed / Unfixed) to indicate the current state.

• Dynamic process detection
  The script now retrieves the process name of the focused window before applying transparency.
  → Enables smarter and broader application of the effect.

Changes

• Switched from single-window to process-wide transparency control
  → Replaced static "A" window reference with process-aware logic.

• Improved tooltip positioning
  Tooltip appears next to the mouse cursor and disappears automatically after 1 second (configurable via titleChangeDuration).

• Refactored transparency logic into functions

  • ApplyTransparencyToProcess(processName, value)
  • UpdateTransparency(processName)

Removed

• Direct WinSet calls on the active window without process context.
• No state tracking in the original script – now managed with:
  • transparencyEnabled
  • currentProcess
