Notify on adding to / removing from favorites
"Add to favorites" shortcut is really toggling "favorability" of the track. It is global (many thanks for that! BTW, "is global" indicator may be useful in shortcuts settings) so when window is minimized (almost always) I'm not sure whether this state is toggled or not. There is in-app notification, but it would be much more useful to have a native desktop notification on this action
Another option is to separate "add" and "remove" hotkeys to prevent accidental undoing required action. When I listen to some favorable track on the radio I am not always sure if I listen it for the first time, so I can accidentally dislike it by pressing "Add to favorites" shortcut again (and with minimized window I wouldn't even notice this)
Any or both of two options would be great
