Burpsuite Plugin

Need to modify Logger++(open source) plugin to filter comments & some key words from all URL logs. the plugin should take required URL as input then it should spider the entire website. from the data set of requests & response the tool should grep / filter all comments & keywords required. we should have a place to key in extra keywords to search for. Finally there should be export option to save the data captured. The Logger++ has all functions required. Only requirement is to customize it and have to remove extra features that are not needed.
