The Open or Create File plugin streamlines repetitive file creation by letting you define custom commands that generate or open files using date-based patterns. Whether you're maintaining daily notes, weekly logs, or recurring checklists, you can automate file naming and folder paths with dynamic placeholders like `{date}`, `{week}`, or `{dow}`. You can also apply time shifts like '+1 day' to target future or past dates, making it perfect for prepping tomorrow's journal entry or last week's review. Each command is fully customisable, with options to use templates and assign unique names for fast access via the command palette. Settings can be exported or imported as JSON, allowing easy reuse or sharing of workflows.
