Feature Request: Make pop-up windows open on the current screen in multi-monitor setup

[jiamingchang]

Description

Currently, when using SwitchHosts on macOS with multiple monitors, pop-up windows (like adding or editing a host) always appear on the primary display. Even if I click the tray menu on the secondary monitor, the pop-up still opens on the primary monitor.

Expected Behavior

I expect the pop-up window to appear on the same screen where I click the tray/menu icon, instead of always defaulting to the primary display. This would improve workflow in multi-monitor setups.

Steps to Reproduce

1. Connect a secondary display to a Mac.
2. Open SwitchHosts and ensure the app is running.
3. Click the SwitchHosts tray icon on the secondary monitor.
4. Observe that the pop-up opens on the primary monitor.

Additional Information

• macOS version: macOS 15.5
• SwitchHosts version: 4.2.0
• Electron apps often use screen.getCursorScreenPoint() or screen.getDisplayNearestPoint() to position pop-ups. Implementing similar logic could fix this issue.

Thank you for considering this feature!
