opensubtitles: Re-enable menu item after Download
After downloading a subtitle, the menu was disabled.
I adapted to the code but may I ask if there is any reason as to why the window is not modal ?
Also, would you like I create a template for the window and split each class into separate files ? It would be easier to maintain.
N.B: I don't know if you are aware but OpenSubtitles API has been deprecated for a REST API. His end-of-life will be end 2023 (if we're still alive until there).
Closes: #532 (closed)
Thanks
