Hello everyone , after update 2020-08-19
if you want to access to F2 now , you need to click F1 or F2 and press down " Crafting Notes " , like in the picture
or you can choose a new key to the Crafting Notes by : Settings => Interface Settings => UI Hotkeys => Crafting Notes , like in the picture
Yeah I was confused too when this happened but I guess they were trying to place everything in one spot. Though I like how it was before but that is compensated by shortcut key to be set manually! I like this update though as is easier for new players to understand! ^_^
