hmm ... like the onx ... as a kind of wireframe I believe it is called - most builders have it as a "blank" starting point. Not just for ease and efficiency - but to me I much more enjoy opening up a design library for inspiration - and then click in the design - let me record a video - ok ?
or just a popup window where I can insert and customize the Radix theme components like in the youtube demo - the youtube demo has layouts - so its different - but it is really visually intuitive to have these wireframes avaliable - when considering a layout
i understand the use of radix primitives - but it is a bit disjointed .... disconnected having a component called button in one style and then radix primitives that are styled to some extent
