The receipts — real demand
“The only reason I have stuck with notability for so long is the geometry and snap to grid capabilities. The most recent update has removed that for ellipses and circles. Rotating ellipses non longer snap to horizontal or vertical alignment when you get close - you just have to eyeball it. The same goes for aligning edges of circles and ellipses with the grid in graph paper templates. I used to love using notability b…”
