I know this is a request based solely on preference, but I thought I would throw it out there all the same.
First let me say that I LOVE this extension. It's wonderful. Kudos to you for creating it, and thank you.
I'm a person who really likes to just keep things simple, so my one beef with it is the "LastFM" item that shows up in my Tools menu within Firefox. I can access all of the options from Firefox's Add-ons menu, so I would really prefer if this menu item wasn't there, or if, at the very least, I had the option to remove it from my Tools menu (if other users liked its presence there).
Not trying to whine, if this doesn't change I am certainly not going to lose any sleep over it, but I just thought I'd throw it out there.
Regardless of whether or not this changes, thanks again for a wonderful extension.
My assumption is that the developer wants to make sure everyone will find the options.
In my case I have other extensions which I need on my browser, five of them created entries for themselves on the tools menu, just like LastFM extension.. so I'm kinda resigned and used to the clutter.. Even if the LastFM dev changed it, the problem wouldn't at all go away for me.
