Is there a way to set default number of columns in gallery? It is set to 3, and currently I change it manually for every gallery in post I create to 4.
Here are the settings on the right https://codex.wordpress.org/images/c/c7/edit-gallery-drag.png
In codex they say "3 Columns is the default settings, which is ideal for most sites.", but not a word about how to change it. I have only found that I can add it to the shortcode ( [gallery columns="4"] ), but this isn't what I need
