This is the current UI
Right now, the current layout wastes a lot of vertical space — especially on laptops or smaller monitors. Here’s what’s breaking the flow:
- The top header and bottom footer take up too much space.
- The footer with just the “Next Lesson” button spans the entire width and height of a full section – that’s overkill for a single button.
- The stacked toolbar/menu layout inside the Jupyter interface eats up even more space.
Why this matters:
When learners are coding and comparing outputs side by side, we need every pixel. Right now, it feels claustrophobic (yes, really), and we constantly scroll up/down just to keep track of what’s going on.
Suggestions:
- Minimize or auto-hide header/footer – Make them collapsible or show on hover.
- Move “Next Lesson” button – Stick it to a corner or float it, don’t let it hog a full strip.
- Compact the Jupyter menus – Merge icon rows or allow toggling toolbars.
This one change can massively improve usability and make the learning experience much more fluid.
Thanks for building this course – just needs a small tweak to go from good to
