Is it possible to add the ability to customise columns, now the names of the columns are fixed and unchanging, it would be nice to be able to customise and add the required column names.
You cannot (and shouldn't) customize the name of Zotero's built-in columns, but you can create custom columns with APIs that are available to plugins.
