ImprovementFaster tab switching and practice start on the learning screen
Switching to the analysis tab, moving through getting started, and starting practice no longer reload the page.
The analysis tab now switches within the screen, and starting practice skips extra page hops. The play table also redraws less often, making it lighter.
Pages are no longer preloaded just because a link is on screen; they load when you're about to tap, which saves data.
