Real-time preview for UI and parameter customization

kcwang · April 1, 2026, 10:21am

Feature description

Implement a live preview window or an instant visual feedback mechanism within the settings menu. When users adjust UI elements (such as colors, spacing, or layout scaling), the changes should be reflected immediately on a sample interface within the settings page, rather than requiring the user to exit to the home screen.

Problem solved

Currently, Symfonium offers an incredible depth of customization, but the “blind adjustment” workflow is inefficient. Users must modify a parameter, back out of several menu layers to the home screen to check the effect, and then navigate back if the result isn’t as expected. This trial-and-error process is time-consuming for a professional-grade app.

Brought benefits

Enhanced Efficiency: Reduces the time spent navigating menus by providing instant feedback.
User Confidence: Helps users accurately identify which parameter controls which specific UI element.
Better UX: Streamlines the onboarding process for new users who might be overwhelmed by the vast number of professional settings.

Device type

Phone

Additional description and context

I truly appreciate the professional depth of Symfonium. Adding this feature would make it the undisputed gold standard for customizable mobile players.

Sorry for the trouble, but I couldn’t find the original issue via search. Could you please provide a link to the duplicate thread? I’d love to follow the progress there. Thanks! Besides, I would like to provide some further context to illustrate the necessity of this feature.

As shown in the attached screenshot, some settings pages (like the one in the bottom right corner) already feature a ‘Show Preview’ button. Without this preview, it would be nearly impossible to identify which specific UI element is being modified by certain parameters.

However, this helpful preview is currently inconsistent and only available on a few select pages. Could you consider expanding this ‘Show Preview’ functionality to all UI-related settings, or at least providing brief descriptive text/tooltips for the more abstract parameters? This would greatly improve the user experience for those of us who rely on Symfonium’s deep customization. Thanks again for your time!"
