From a Bubble background (as I know you are 😉) think of the formula editor as the equivalent of the expression builder. So rather than saying "Insert Dynamic Data" and then creating an expression, you instead click the "fx" button and add a formula to generate a dynamic value/output etc. The workflow editor is pretty much the same as workflows except you add the action steps top-to-botton rather than left-to-right. Workflows are in response to an event, like in Bubble, such as button clicks. Workflows do not play quite the same central role in the logic of your app as they do in Bubble and at first glance do not appear as comprehensive in terms of the actions you can perform. That's because Toddle is much more reactive by utilising variables for binding dynamic values to elements etc and that's also why the formula editor is perhaps more central to Toddle than the expression builder is in Bubble. Variables are the equivalent of Bubble's custom states but much more useful and flexible eg create your own custom objects (data types) as variables which you cannot do in Bubble, Bubble only supports custom data types as either physical database records or API calls, which quite frankly is a massive weakness and a pain in the rear end when using Bubble. Hope that helps.
