For years and years I have used templates, libraries, plug-ins, and tools to try to make my web sites and apps work. But it always requires compromises. That PDF or PowerPoint conversion is a bit of, the blog looks good but I could have been better.
It is incredibly satisfying to write the things directly now. Dragging and dropping slides (from click, to drag, to drop), writing shapes into a PDF file one by one, cropping image bitmaps and being completely in control (and responsible) for image optimisation (file sizes, processing time).
