Addon: Cron Task Scheduler
This addon designates the current card in the reviewer as a cron card. A cron card follows a schedule from the assigned expression. This is useful for reminders and small notes kept in flashcards.
@daily: Repeats the card once per day.
@hourly: Repeats the card every hour.

When changing configs, you can test out your syntax with this site: https://crontab-generator.org
Reviews will be scheduled based on Anki’s notion of time and timezones. Day scheduled cards are converted to review cards (Anki-time) and intraday scheduled cards are converted to learning cards following Unix Epoch time. Any time specific information beyond “today” is discarded, as Anki-time only records dates.
Also, scheduling a card for the next day will not show up until 4 AM under Anki’s default config settings. This can be changed under the “Next day starts at” option in preferences.
Cron table is saved in user’s media folder in a file called “_crontab”.
Backups are named “_crontab.bak” and “_crontab.ba2”
Problems with other button timer manipulation addons could be resolved by changing the addon file/folder name so that cronholio gets loaded first before any other addons.
Since these are scheduled task without any changes to interval, no logging methods are coded in this addon.
