Flex Block Name and Preview
In update 1.2 we added the option to name the blocks to easily differentiate between them without having to access each.
To do that either click on the block to activate it, inside your page editor, click on its title and write the new name.
Or you can access your Flex Builder’s editor, tap on its name in the top left corner and add the new name for it.
Another option that we believe will greatly help you with identifying your blocks built with Flex is the option to add a screenshot preview. All you need to do is enable the Screenshot On Save option and it will save your new blocks with a preview image.
NOTE: If the screenshot option is enabled, saving the FlexBlock will take a bit longer than usual. Also note that the screenshot option is disabled by default.
