I finally got a chance to try to use clippings for researching a short paper I have to write. I was able to save lots of info as clippings and I tagged them along the way. The thought was that I could then rearrange all the cards to the different sections of my paper.
Unfortunately, there is no way to filter by tags. In fact, tagging individual clippings seems nearly useless. Additionally, dragging cards is terribly slow when trying to scroll off screen.
Clippings seemed like a nice feature, but it is very clunky and nearly unusable for more than about 10 clippings.
