On the client platforms, the metadata is stored in SQLite databases.
For the Reminders implementation, a reminderOrder field was added to control sequencing and "pinning"
This is straightforward, but complicated by the duplication for each platform.
>>It will take time to update all of the presentation modes they offer (desktop, web, etc), but once again this is a relatively straight forward feature. They already have a segment of code which orders notes, and which places notes with reminders at the top of the list. It should be a day per mode to change and test code to "pin" a note at the top.
Again complicated by the duplication for each platform.
Not sure how straightforward it would be; the simplest UI would be right-click on the note and pin to the top.
