Feature Request : Web Clipper : Highlight Text

Hello,
Would be awesome :

1. to select a text in the web page and add it to a field
2. highlight the text of the webpage according to a field
3. and the extension should retrieve previous data from it’s URL (very handy for note taking)
4. this would also perform “search engine” on notes / highlights

There is a Chrome Extension that highlight an URL call liner
Thanks !
