Mail Categorization

**Is your feature request related to a problem? Please describe.**

There is no feature to help users to sort out some very important emails they want to separate out from all other.
Wanted to build some kind of categorizer so that user can be prompted and told that what email to look where, there could be a filter mechanism so that users can filter based on AI categorised, They later could manage the categories in the settings tab as well.

**Describe the solution you'd like**

I would like a feature that automatically categorizes important emails for users using AI-based classification. The system would analyze incoming emails and suggest categories such as "Urgent," "Work," "Personal," "Finance," etc. Users would receive a prompt indicating which category an email belongs to, making it easier to prioritize and manage emails.

Additionally, the users should have the ability to filter emails based on these AI-generated categories, and they should be able to manage and customize the categories via a settings tab. This would include options to rename, add new categories, or adjust the AI's categorization rules to better suit the user's preferences. The goal is to help users quickly locate and act on critical emails without getting lost in their inbox.

**Detailed Steps**

1. AI Categorization:
- Implement an AI-based system to automatically classify emails into predefined categories (e.g., Urgent, Work, Personal, Finance, etc.).
- Use NLP models (e.g., BERT, GPT-3) or cloud services like Google Cloud NLP or AWS Comprehend for classification.

2. UI/UX:

- - Display category labels (e.g., “Urgent”, “Work”) next to emails in the inbox.
- - Allow users to manually adjust categories and provide feedback (thumbs up/down).
- - Filtering and Search:
- - Add filters to show emails by category (e.g., filter by “Urgent” or “Work”).
- - Enable category-based search (e.g., search only within "Finance" emails).

3. User Customization:
- Create a settings tab for users to manage and customize categories (e.g., rename, add new categories, adjust AI rules).
- Provide users the option to disable categorization for specific types of emails.
