 ## Features
 
 * Fulltext indexing of documents
+  * The `Index All` button tries add every file not already indexed to the index
 * Custom regex based tags (see https://golang.org/pkg/regexp/syntax/)
+  * The `Retag All` button will reapply the current tags to all indexed documents
 * Password hashing using BCrypt
 * 2FA using TOTP
 * Content Security Policy
