Code review comment for lp:~mycompostpile/cairo-dock-plug-ins-extras/YoutubeDl

Hello

Thank you for this new applet! :)

I just quickly tested it and it seems working fine!
I just have a few ideas/suggestions:
 * If the download directory doesn't exist (by default ~/Videos), there is a problem but it's not explained what's the problem.
 * I also suggest to use the translated name for the default folder (check this file ~/.config/user-dirs.dirs or use the output of this command: xdg-user-dir VIDEOS )
 * By default, it's maybe better to use Cairo-Dock's dialogues instead of pynotify (or at least having an option to use these dialogues)
 * Why do you use a list in the dialogue when we do a left click?
 * For the 'Applet Help' dialogue, you can use a 'ShowDialog' with a timeout of 0 (and no button)
 * About this dialogue, there is another entry in YoutubeDL / Applet's Handbook: what's the difference?

PS: now you can use this command to sync with the master branch: bzr pull lp:cairo-dock-plug-ins-extras
