Toggle Watched/Unwatched Ticks

I'd just like to say thanks for all the work put into the skin and the forums, it really is the best skin!

I hope this hasn't been asked already, i did search the forum before posting.

Is it possible to toggle the watched ticks that appear in library and file mode. I know it is possible to toggle the ticks with 'w' for each individual file, however I'm looking for a setting somewhere to toggle the whole feature off so that it never shows the watched ticks?

Thanks
