+# 202_109 Show name field in Comment plugin floating toolbar
+
+### What
+The `focus-hidden-icons` override for the Comment plugin had an empty body, which
+suppressed all hidden child input widgets from the focus toolbar. Added
+`(dynamic (string-input-icon t 3))` to show the author name (by) field at child
+index 3, allowing users to modify the comment author name directly from the
+floating toolbar.
+
+### Why
+The name (by field) of a comment could not be modified from the floating toolbar,
+requiring users to use workarounds to change the comment author.
+
+### How
+In `TeXmacs/plugins/comment/progs/various/comment-menu.scm` (line 70-72), the
+`focus-hidden-icons` menu for comments had an empty body that suppressed all
+hidden child inputs from the toolbar. Added `(dynamic (string-input-icon t 3))`
+to render the author name input widget:
+
+```diff
+ (tm-menu (focus-hidden-icons t)
+-  (:require (any-comment-context? t)))
++  (:require (any-comment-context? t))
++  (dynamic (string-input-icon t 3)))
+```
+
+Child index 3 corresponds to the `by` (author name) field in the comment tag
+structure: `(unique-id mirror-id type by time src body)`.
+
+## How to test
+1. Open Mogan and ensure the `comment` style package is loaded
+2. Insert an unfolded comment via `Insert -> Note -> Unfolded comment`
+3. Click on the comment so the focus toolbar appears at the top
+4. Verify that a "By:" input field is now visible in the floating toolbar
+5. Change the name in the input field and confirm the change is applied to the comment
