Provide a More Robust Error Handling Mechanism: Each method should have exception handling to ensure that any errors that occur during the execution of a method are appropriately caught and dealt with. This is especially important for web interactions as many things can go wrong (e.g., a page failing to load, a page layout changing so an element can't be found, network issues).
Add Support for More Web Interaction Functions: The current implementation provides basic functions like clicking, typing, and navigation. You could extend these functionalities to handle more complex interactions such as dragging and dropping elements, dealing with pop-ups, or handling iframes.
State Management: A session management system could be beneficial to allow users to pause and resume their browsing session. This would involve storing the current state of the browser and restoring it when the user continues.
Better Image Handling: Currently, images are rendered as their alt text. You might want to consider implementing a feature that can perform image analysis or OCR (Optical Character Recognition) to provide more information about images when necessary.
Advanced DOM Navigation and Interaction: Add methods to interact with complex elements like sliders, dropdowns, or menus. Furthermore, instead of using a simplified DOM, consider using a full-fledged headless browser, which can provide more realistic interaction and better JavaScript execution.
Support for Asynchronous Actions: Some actions on the web are asynchronous, such as AJAX requests. Your plugin could have some support to handle these situations, like a "wait for element" feature.
Customizable User-Agent: Allow the user-agent string to be set by the user, to mimic different browsers or devices.
Proxy Support: Some users might want to route their requests through a proxy. Providing support for this can be helpful.
