I cannot find any mechanism to do a tree-wide (or column-wide or card-wide) search and replace operation, much to my chagrin. I’m starting wonder if the feature exists at all. Any tips?
If not, then I suppose this is really a feature request. Find/Replace is found all authoring tools in some form, and adding it to Gingko seems to fulfill the criteria laid out in the dev philosophy post - all user personas would find it useful, the concept is simple rather than complex, and can be implemented as a logical extension of the existing search tools.
