Configuring the settings doesn't help with the problem of it being too opinionated. Changing the settings wasn't the problem. The fact that there were settings was. For instance, there really shouldn't be border-radius or box-shadow on .panel at all. That should be up to the designer/front-end person/whoever to add. That's a very subjective property and has nothing to do with the basics of its layout or how it functions. Having a bunch of declarations of box-shadow: 0; all over the place is just clutter. That's just one example of many. I should clarify, I am not anti-Bootstrap. I use bits and pieces of it all the time. It's just not very good for building a large, scale websites that serves many purposes. And I can't design every page and app that comes my teams way, so I'm glad that there's something my coworkers can use that won't look like an unthawed caveman (from 2002) built it.
