In this release
• Added new 768-step ultra-wide palette: “Starry Night [UW].”
• UI tweaks
Julia Sets
Explore Julia Sets directly from the Mandelbrot Set. Single-tap any Mandelbrot point to generate the matching Julia Set from that exact complex value, then single-tap again in Julia mode to return to the exact Mandelbrot view where you started.
This update also saves Julia constants in bookmarks and shared bookmark files, shows the active Julia `c` value in the HUD, improves Julia rendering at deeper zoom levels, and refines iPad controls with a cleaner utility row above the floating toolbar.
- Tap any Mandelbrot point to create its matching Julia Set.
- Tap again from Julia mode to return to the exact Mandelbrot view.
- Julia bookmarks and shared bookmark files now preserve the source `c` value.
- The HUD now shows the active Julia constant.
- Julia set deep-zoom rendering and iPad controls have been refined.
