Good no frills plugin! Does exactly what it says it does.

I tried Q2W3 Fixed Widget, Sticky Menu (or Anything!) on Scroll, and myStickymenu but this plugin seemed to work well. Works right out of the box and seems less bloaty and glitchy than the other three. I am using it for a sticky widget sidebar. Was using Q2W3 for many years, however, with my new website it was conflicting with way too many plugins and it hasn’t been updated by plugin author for almost a year.
