Describe the feature you'd like to request
The idea is to allow the user uploading the video to choose between two types of thumbnails, if they wish. The current behavior enables users to select a thumbnail from video frames or upload a custom image. What do you think about allowing users to upload two images (if desired), with one designed for the dark theme and the other for the light theme?
Advantages:
- Thumbnails could blend better with the theme chosen by the viewer


Disadvantages:
- Potential reduction in the creator's recognition if they opt for different thumbnails for dark and light themes. In this case, the uploader would ideally only change the main background color while retaining the recognizable elements of the thumbnail.
