This are Volto addons or modifications that don't fit a specific purpose but are generic enough to fit more then one website.
Try to group components (Blocks, Views, Widgets) by their big specific idea. For example, the PlotlyChart folder hosts the Block View, Block Edit and Modal Chart components.
Name content type views as View.jsx. Name block views as BlockView.jsx, block edit as BlockEdit.jsx, widgets as Widget.jsx
- Set the Hidden widget as default widget for the blocks field
