 * __MAX_CONCURRENT_DOWNLOADS__: Maximum number of simultaneous downloads allowed. For example, if set to `5`, then at most five downloads will run concurrently, and any additional downloads will wait until one of the active downloads completes. Defaults to `3`. 
 * __DELETE_FILE_ON_TRASHCAN__: if `true`, downloaded files are deleted on the server, when they are trashed from the "Completed" section of the UI. Defaults to `false`.
 * __DEFAULT_OPTION_PLAYLIST_ITEM_LIMIT__: Maximum number of playlist items that can be downloaded. Defaults to `0` (no limit).
+* __CLEAR_COMPLETED_AFTER__: Number of seconds after which completed (and failed) downloads are automatically removed from the "Completed" list. Defaults to `0` (disabled).

@@ -43,6 +44,7 @@ Certain values can be set via environment variables, using the `-e` parameter on
 * __AUDIO_DOWNLOAD_DIR__: Path to where audio-only downloads will be saved, if you wish to separate them from the video downloads. Defaults to the value of `DOWNLOAD_DIR`.
 * __CUSTOM_DIRS__: Whether to enable downloading videos into custom directories within the __DOWNLOAD_DIR__ (or __AUDIO_DOWNLOAD_DIR__). When enabled, a dropdown appears next to the Add button to specify the download directory. Defaults to `true`.
 * __CREATE_CUSTOM_DIRS__: Whether to support automatically creating directories within the __DOWNLOAD_DIR__ (or __AUDIO_DOWNLOAD_DIR__) if they do not exist. When enabled, the download directory selector supports free-text input, and the specified directory will be created recursively. Defaults to `true`.
+* __DEFAULT_DOWNLOAD_FOLDER__: Default subdirectory within __DOWNLOAD_DIR__ (or __AUDIO_DOWNLOAD_DIR__) to pre-select in the download folder field. Useful when most downloads should go to a specific subfolder. Can be overridden per-download in the UI. Defaults to empty (uses the base download directory).
 * __CUSTOM_DIRS_EXCLUDE_REGEX__: Regular expression to exclude some custom directories from the dropdown. Empty regex disables exclusion. Defaults to `(^|/)[.@].*$`, which means directories starting with `.` or `@`.
 * __DOWNLOAD_DIRS_INDEXABLE__: If `true`, the download directories (__DOWNLOAD_DIR__ and __AUDIO_DOWNLOAD_DIR__) are indexable on the web server. Defaults to `false`.
 * __STATE_DIR__: Path to where the queue persistence files will be saved. Defaults to `/downloads/.metube` in the Docker image, and `.` otherwise.
