Multiple pip windows of the same screen, each with unique crop areas

I'd like to suggest a feature that would significantly enhance the usability of Better Display for people using wide-screen monitors.

Use Case Explanation:
For long web pages, PDFs and documents, and other applications that don't natively support multiple columns, the content uses only a narrow portion of the screen, leading to wasted space on wide monitors and unnecessary scrolling.

Better Display can solve this issue by allowing the creation of a virtual screen that is:

1. Very narrow but extremely long.
2. Paired with multiple Picture-in-Picture (PIP) windows that display different crop areas of this virtual screen side by side on wide monitors.

Example Setup:

1. Create a virtual screen that is very narrow and extremely long (e.g., 500px wide, 5000px tall).
2. Use multiple PIP windows to display different crop areas of the virtual screen side by side:
   • PIP 1: Displays the top 10% of the virtual screen, positioned in the first column of the wide monitor.
   • PIP 2: Displays the second 10% of the virtual screen, positioned in the second column.
   • PIP 3: Displays the third 10%, positioned in the third column, etc.

In this configuration, the application perceives it is rendering a single, narrow, and long document or webpage, while Better Display splits that long view across multiple columns on the wide monitor, providing a seamless reading experience with minimal scrolling.

Broader Applicability:
This feature could also be useful for other use cases, such as:

1. Displaying different segments of the same application side by side for comparative analysis.
2. Monitoring different regions of a software interface simultaneously.
3. Improving multitasking by allowing users to visualize multiple sections of a dashboard or development environment at once.

Current Limitation:
Currently, Better Display only allows one PIP window per virtual screen, limiting the ability to implement this concept fully.

Proposed Solution:
Allow multiple PIP windows from the same virtual screen, each with unique crop areas.

Benefits:

1. Enhanced productivity for all wide-screen monitor users.
2. Improved reading experience for long web pages, documents, and other applications.
3. Innovative multitasking and visualization approach for various software applications.

Thanks for considering this feature request! I believe it would add substantial value to the Better Display tool.
