Notepad by InBasic

This extension provides a full-featured WYSIWYG HTML Editor with all popular formatting styles like those that all modern editors provide. You can have multiple notes organized notes in different directories (notebooks). The extension automatically saves your changes and hence there is no need for the manual saving. The extension is integrated into the right-click context menu so that you can append the currently selected text to a note of your choice from the right-click menu without actually opening the editor. The UI of this editor can be loaded in a browser tab or as a separate window. To change the operation mode of the extension use the toolbar button's right-click options.
