Additional roadmap for feature enhancement

[JeanTracker]

Please review this features.

• support for analysis of huge files (>50MB): doesn't work this extension when huge file is opend.
• support for control filters by group: It is inconvenient to control filters one by one. A feature will be added to group filters according to their purpose and control them collectively.
• support for filter group management: Add a feature to manage filter groups as files within the extension.
• support for exclude filters; Even after applying filters, unnecessary information may still be included. Removing meaningless information would aid in issue analysis.

Hi! These are good features to have~ However, for PR I think the convention is to accept code implementations. If you have implemented the features, pls feel free to send a new PR/several PRs and otherwise you can open a new issue or reply to the existing issues.
