Here is a draft response:

@edreisMD, I have started working on this PR to expand the description for the get_plugins() function in the README.md file. My plan is to:

1. Review the get_plugins() function definition and usage examples in README.md.
2. Add more details on the available filters like 'working', 'ChatGPT', 'langchain', and category names.
3. Provide some examples for each filter.

Give me a minute!
