All .srt files and .vtt files are named the same as the media file.

Mkv-Watcher now logs less but more relevant info into the system log for the systemd service.
Added screen aspect ratio for viewing media. this is remembered by the web browser
Fixed upload file button with a progress bar popup when adding a new media file
