(1) Add a feature that enables a user to convert the "Extension Window" to instead to a "new tab"... Maybe add it also as a setting default option... "Open tabox initially: as an extension window / as a new tab". (2) In the expanded list of tabs view, on the far right-side of the collection name line and the far right-side of each tab line, add a "note" icon to the existing group of items... upon clicking, allows a user to add and save a personal text note(s) regarding the collection itself and/or for the tab. Thank you.
