Feature Request: Enhance Subtitle Selection with Custom Input Tags

[xHyperVoid]

Problem Statement
The current subtitle selection uses a predefined list in a multi-select dropdown. This system often fails to select the user's preferred subtitle if the subtitle's language label does not exactly match the option in the list. For example, a preference for English will not match subtitles labeled ENG, EN, or English (US).

Proposed Solution
I propose replacing the current multi-select dropdown with a more flexible multi-select combobox that accepts custom user inputs (tags). This would allow users to define their own criteria for subtitle matching.

Example Implementation:

Benefits
This change would significantly improve the user experience by:

• Increasing Flexibility: Users could add multiple aliases for their preferred language (e.g., English, ENG, en-US) to cover all common naming conventions.

• Improving Detection: The system would be able to match a much wider range of subtitles automatically, reducing the need for manual intervention.

• Enhancing User Control: It gives users more precise control over subtitle prioritization, ensuring their preferred language track is reliably selected.
