Rich Text Note Option on Each Mind Map Section/Box Rather Than only One Central Note For The Whole Dashboard

There should be a rich note writing option available  to each section/box in a mindmap. This is the only reason I am not switching from Mindomo. I need a note taking option to keep related article, photo or link  etc. segregated into each of the mindmap branch/section/box. This helps to find the related article or link to a specific section of the map easily because they have been noted down right where they are most needed/relevant.
