Is there a place to record suggestions for the developers, once they clear the backlog of actual problems? I will note that they are doing a FABULOUS job of getting that done, so I see a list like this of being great use in the near future.
For example, in both Keap and Infusionsoft, in the Broadcast builder, it would help to have a 4th type of text, called Disclaimer that is smaller that the main body.
Option 2 on that would be to give control over the type sizes throughout the document. Sometimes it is very effective in the copy to put 1 word a few points larger than the rest.
