Org Mode: Create a quick timestamped note and capture a screenshot

I wanted to be able to quickly create timestamped notes and possibly capture a screenshot. Prompting for a value inside an org-capture-template disrupts my screen a little, so maybe this will make it as easy as possible. I could probably do this without going through org-capture-templates, but I wanted to take advantage of the fact that Org Mode will deal with the date tree and finding the right position itself.

(use-package org
  :config
  (add-to-list 'org-capture-templates
               '("p" "Podcast log - timestamped" item
                 (file+olp+datetree "~/orgzly/timestamped.org")
                 "%<%H:%M:%S,%3N> %^{Note}"
                 :immediate-finish t)))
  (defun my/org-capture-prefill-template (template &rest values)
    "Pre-fill TEMPLATE with VALUES."
    (setq template (or template (org-capture-get :template)))
    (with-temp-buffer
      (insert template)
      (goto-char (point-min))
      (while (re-search-forward
              (concat "%\\("
                      "\\[\\(.+\\)\\]\\|"
                      "<\\([^>\n]+\\)>\\|"
                      "\\([tTuUaliAcxkKInfF]\\)\\|"
                      "\\(:[-a-zA-Z]+\\)\\|"
                      "\\^\\({\\([^}]*\\)}\\)"
                      "?\\([gGtTuUCLp]\\)?\\|"
                      "%\\\\\\([1-9][0-9]*\\)"
                      "\\)") nil t)
        (if (car values)
            (replace-match (car values) nil t))
        (setq values (cdr values)))
      (buffer-string)))
(defun my/capture-screenshot (time &optional note)
  "Capture screenshot and save it to a file labeled with TIME and NOTE.
Return the filename."
  (interactive (list (current-time) (read-string "Note: ")))
  (let* ((filename (expand-file-name
                        (concat "Screenshot_"
                                (format-time-string "%Y%0m%d_%H%M%S" time)
                                (if note (concat " " note) "")
                                ".png")
                        "~/Pictures"))
         (cmd (concat "spectacle -b -o "
                      (shell-quote-argument filename))))
    (shell-command cmd)
    filename))
(defun my/capture-timestamped-note (time note)
  "Disable Helm and capture a quick timestamped note."
  (interactive (list (current-time) (read-string "Note: ")))
  (let ((helm-completing-read-handlers-alist '((org-capture . nil)))
        (entry (org-capture-select-template "p")))
    (org-capture-set-plist entry)
    (org-capture-get-template)
    (org-capture-set-target-location)
    (org-capture-put
     :template (org-capture-fill-template
                (my/org-capture-prefill-template (org-capture-get :template)
                                                 (format-time-string "%H:%M:%S,%3N")
                                                 note)))
    (org-capture-place-template)
    (org-capture-finalize)))
(defun my/capture-timestamped-note-with-screenshot (time note)
  (interactive (list (current-time) (read-string "Note: ")))
  (kill-new (my/capture-screenshot time note))
  (my/capture-timestamped-note time note))

Then I can call it with h h n for my/capture-timestamped-note or h h i for my/capture-timestamped-note-with-screenshot via keyboard shortcuts defined elsewhere in my config (see my/key-chord-commands).
