This tool can be interesting for every person who publishes many similar comments on one or different sites and needs a place for their storage and quick access

After installation, the extension will be empty. During the first run, a database will be created in your “cookies and temporary Internet files”, so all the data you enter will be saved only on your personal computer and no one else will see it. 

The main window of the program consists of 3 pats: Search, Elements tree, Visualization area

Elements tree represents the structure and helps to find the required comment. 
If enter something in the search, it will leave only folders and comments, whose names at least partially coincide with the written text.

After the comment is selected or checked, visualization area will display its content and you can copy and paste them on any site or anywhere else

This extension allows you to add, rename or delete items in the tree using the pop-up menu of the element

Extension also monitors the state (closed, selected or checked) of all items, and it will save this state until next start. If you do not need previous state of the elements and do not want to uncheck or close them one by one, you can reset the state of all elements through the pop-up menu

All comments may have multiple sections with a section name and content
If check multiple comments, visualization area will group its content by the section name. Also it is possible to show or hide section names during visualization.
