New options added at v1.2x

• SaiSuke will remind you to update the sync period when it's been new month. There is an option in 'Calendar Update Setting' to disable this reminder.
• Sync frequency option allows you to select how often the calendar will be sync'd. If the calendar is not updated frequently, such as 'Holiday Calendar', you can select 'Once a month' or 'Once a year' to reduce the sync process time.
