So far nothing has happened

I added a title (no font selection available) and a picture (no adjustment of the picture available). I wanted the text over the picture in a certain spot, but that was also not available. Not much creativity there yet. I wanted to add video, but it did not show up to select from.
Then to test the system, I selected publish and it hung up at processing. I tried again, nothing. I sent an email to the developer... waiting for a response.
