I'm trying to do some simple stuff here. I'm not a graphics designer but I have to have a tool to create book covers to submit to CreateSpace. Affinity Designer, according to reviews seemed to be the right app. Maybe not. I've finally got a file, created with many layers, that hopefully will be a book cover. I need to export the whole thing to a PDF. In other applications I've been able to "flatten layers," or combine all layers into one document, then export to JPG, PDF, or whatever. With Affinity Designer I can't figure out how to do this. Whenever I export, even though I say I want the entire document, I only get a few of the layers. Seems to me it should be a simple task to combine all layers into a single image, then export as a PDF document, but I can't figure out how to do this and all the help files and videos I've searched and read don't seem to get down to this level of simplicity. Can anyone help?

Thanks for the help!

This is just a simple question, but I've spent too much time searching elsewhere. Where is the frame text tool? In the help file, the icon for it is a square with an upper case T inside. I see the artistic text tool, pen, pencil, vector brush... No frame text tool. I've selected the layer I want to put text in. I can't find the icon and I can't find a menu choice to insert text.
