What is Solo?

I find "Solo" and "de-Solo" in the stickie's drop-down box. i have no idea what it does or means.
Please enlighten me.

You know, Hans Solo of the SW franchise! 

Why don't you try out the solo feature. It's pretty obvious what it does and how it got its name, and I promise that nothing bad will happen. If you don't like it, then de-solo the sticky to return to normal. I usually keep one sticky in solo mode to clear my desktop of unorganized stickies. It allows me to temporarily sweep away my mess instead of cleaning it up more permanently.
