I’ve been working on a photobook project and i really hate the app called scribus, so i want to use figma slide for a replacement. I haven’t worked with figma slide a lot but i think we could have some feature such as

1. Linking Textbox for displaying text in two seperate coloumn 
2. Page number on the left side for left pages, and on the right side for right pages. (autometically adjust them when adding a new page)
3. create new slidw based on a template layout (like google slides) and be able to adjust the template slides
4. Layout guide for margins and text area
5. Adjustable slide sizes (i think someone already metioned it)
6. (Maybe) have something for editing pictures brightness like how it is in design files
7. some shotcut in the design files (K for scaling)
8. Some way to export the slides to pdf or png or jpeg

I really love using design and figjam and it is really painful to use scribus,  but it has some feature figma doesn’t have right now so i have to use it (like checking dpi). I understand that the slide might not be aiming for those feature but i think it would be nice if i can use it to create photobook. Also i haven;t used figma slides that much so i might be wrong
