 The following features are under consideration
 for future releases of the plugin:
 
-### Batch Image Processing
-
-- **Extract from all embedded images** in a note at once.
-- **Process entire folders** of image files (e.g., screenshots, scans).
-- **Configurable output** options for batch mode:
-  - Combine all results into the active note.
-  - Create a new note for each image.
-  - Optionally include image filenames as headings or titles.
-  - Separate output configuration for single and batched extractions.
-
-### Multi-image Request Batching
-
-When performing batched image processing:
-
-- **Send multiple images in a single API request**
-  to reduce latency and API overhead.
-- Use a defined **separator string** between images'
-  OCR results for reliable parsing into output.
-- Improve efficiency and lower cost when working with high-volume image sets.
-
-### Enhanced Output Templates
-
-Use the following dynamic properties in addition to date-time
-in output templates:
-
-- **Model and Provider names**: Use `{{model}}` or `{{provider}}`
-  in output templates.
-- **Image metadata**: Use image metadata in output templates, such as:
-  - `{{image.filename}}` for the original filename
-  - `{{image.path}}` for the full path of the image
-  - `{{image.size}}` for the image size in bytes
-  - `{{image.dimensions}}` for the image dimensions (e.g., "1920x1080")
-  - `{{image.width}}` for the image width
-  - `{{image.height}}` for the image height
-  - `{{image.created}}` for the image file creation date
-  - `{{image.modified}}` for the image file last modified date
-- **Note properties**: When outputting to a note, use:
-  - `{{note.title}}` for the note title
-  - `{{note.path}}` for the note path
-  - `{{note.created}}` for the note creation date
-  - `{{note.modified}}` for the note last modified date
-  - `{{note.frontmatter.key}}` for any frontmatter key-value pairs
-- **Other metadata**:
-  Any other relevant metadata that can be extracted from
-  the image file or note.
-
-### Other Potential Enhancements
-
-- **Custom provider name**: Allow custom naming when using custom provider.
-- **Custom model name**: Allow setting a custom name for any model used.
-- **Preview before extract**: Show a list of matched images before running OCR.
-- **Hide or obfuscate API keys**: Hide or obfuscate API keys in settings.
-- **Support for more OCR models**, including local or offline alternatives.
