Recently, we were debugging some performance issues with a client's Drupal Commerce website. After doing the standard optimizations, we hooked up New Relic so we could see exactly what else could be trimmed.
I've been doing a lot lately with Grunt and LibSass within my drupal.org contrib theme, Gratis. Yesterday, I updated my Node modules locally. Shortly thereafter, I started getting a nasty Drush error.
One current trend in the world of web design is to limit the display of certain design elements unless specifically called for. This serves to clean up the page design and helps prevent over-cluttering.
