The Template Filename plugin enables you to create notes with fully customizable filenames based on dynamic variables like timestamps, counters, and system info. It supports an extensive set of placeholders for date and time formatting, random strings, base-converted Unix timestamps, and sequential counters. You can also inject system values like username or device name, and apply text transformations such as slugifying or changing case. A live preview helps visualize the final filename before creation, and default templates can be saved for faster note generation. This is especially useful for users managing structured logs, journal entries, or autogenerated content based on repeatable naming schemes.
