User Problem

Currently, Trello does not automatically switch between a white (light) background during the day and a black (dark) background at night within the planner or board interface. This makes it less comfortable for users who prefer the UI to synchronize with their device's day/night mode (dark mode), as is common in many modern apps and operating systems.

Suggested Solutions

Enable Trello to automatically switch between light and dark themes (including white and black board backgrounds) based on the device/system's day/night mode or user-specified schedule. Ideally, provide an option in Trello settings to "Match system theme" so that the interface adapts dynamically to the device's dark or light mode.

Current Workarounds

None available for full automatic day/night background switching within boards.
