Buttons, formulas and packs can be used either on the pages (canvas) or in columns.
Buttons have a name. A description, which can be formula driven, and an action. You can select one of several predefined actions from the drop down, or you can add your own formula action. A special action is runActions(), which allows you to chain a number of other actions together.
There are currently about 200 standard formulas, including decision formulas (if() and switchIf() ), Loops forEach() and various filters (filter(), sumIf() etc).
It is also possible to add your won, or use other people’s formulas created in packs.
