Snooze your code, doc, feed in Emacs
The package can be installed via MELPA. The package name is org-snooze.
Focus on the active file buffer, then use M-x org-snooze. It would asks you to set a snooze time.
Then Emacs would remind you at the given time through Emacs appointment reminders
(appt.el). You can edit other files after that. When it is at your setting time, you get a
notification. Finally, use M-x org-snooze-pop to get back to your snoozed file at the line where you leave.
M-x org-snooze-pop always pops the most recently alerted but unprocessed snoozed item.
Note that if you want some fancy functionality like system notification and sound alert. Please check my appt config at here.
