I use Reminders in DevonThink once in a while, and find it can be a useful feature (testing the send email feature now, and other options). However, I see something missing to the options.
It is possible to set up a reminder to trigger Hourly, Daily, Weekly, Monthly or Yearly, but I see no indication of a place to set up an end hour or date. I find that a bit annoying, as I would like to set up a daily reminder for only one week. It would be also got for that reminder to skip weekends for example.
Additionnally, I don’t know if you can set it up to show the Annotations or other specific text to be included in an email.
