Add customizable player progress bar styles

Problem Description

I would like to suggest adding the ability to change the style of the player progress bar in settings.

Possible styles could include:

• Default thin line style
• Wave / fluid style
• Rounded / thick bar style
• Additional optional styles in the future

The user should be able to switch between styles depending on personal preference.

Proposed Solution

I would like to suggest adding the ability to change the style of the player progress bar in settings.

Possible styles could include:

• Default thin line style
• Wave / fluid style
• Rounded / thick bar style
• Additional optional styles in the future

The user should be able to switch between styles depending on personal preference.

Alternative Solutions

If full customization is too complex, a simpler approach could be:

• Add 2–3 predefined styles for the progress bar
• Keep the current default style as the standard option
• Optionally expand customization in future updates

Additional Context

This feature would improve personalization and make the player feel more modern and flexible.

Since other UI elements already have some level of customization, extending this to the progress bar would improve consistency across the app.

No files, tests, or specific player and settings entry points are named. Start by locating the progress bar implementation and the settings UI, then determine which predefined styles are feasible and how the selection should persist. Done means the chosen style is applied consistently and the existing default remains unchanged.
