Add Small Window feature

[Korb]

Is your feature request related to a problem? Please describe

I need a widget that displays a miniature view of the WiFiAnalyzer application running in the background on top of the current application.

Describe the solution you'd like

The Small Window (aka picture-in-picture mode) feature allows you to display a window overlaying other apps and pin it to the edge of the screen as an always-on small label. The label can be freely moved along the side edges of the screen.

Describe alternatives you've considered

Split-screen

Very interesting idea, sorry to say all current contributors are busy with other work. When we don't have an opportunity or time to implement a feature, we encourage developers to fork the project and become a contributor. It would be great to add new contributor to this project. Looking forward to your PR.

After further investigation of the request, we found that implementing a "Small Window" (floating overlay) feature is not feasible due to Android platform limitations and WiFiAnalyzer's privacy principles:

• Android restricts background Wi-Fi scanning for privacy and battery reasons. When WiFiAnalyzer is not in the foreground, it cannot continuously update Wi-Fi data.
• Overlay windows require special permissions (SYSTEM_ALERT_WINDOW), which are discouraged for privacy-focused apps and may negatively impact user experience.
• The app's activity is paused in the background, preventing live UI updates.
• WiFiAnalyzer prioritizes minimal permissions and user privacy, in line with its open-source and GPLv3 commitments.

For these reasons, the requested feature is not compatible with WiFiAnalyzer's goals and Android's security model.
