Improve StoryMap and Map on Arcgis online

[CélineLE_HIR]

Hello,

Would it be possible to develop a spell checker, especially in French ?

Would it be possible to justify a text, in addition to centering it...?

Would it be possible to have more font, including "Calibri" ? 

Would it be possible to center titles and subtitles?

Would it be possible when I reduce my card to the side to be able to put in front of images and videos and not only text? Currently the images and videos go below

Would it be possible when I set the pop-up window of my map on arcgis online to display attachments as images and not just as a link ?

Thanks in advance,
