Please provide feedback when “Copy Tor Log messages” is clicked
Copying Tor log messages to the clipboard is great. But it requires that user understand how the whole thing works. I've seen users regularly thinks that the button “did nothing” when it was clicked.
A feedback in the form of a non-modal, transient, notification would probably help. The message could say “513 Tor log messages now ready to be pasted in any text editor”, or something like that.
