Image Sequencing

Currently the image sequencing doesn't work well on mobile devices or apps , because the each block is too big, and you can not see all the blocks or at least most of them, they are all underneath each other. How can I change the size of the blocks , so more can be seen in mobile mode. Great Thanks

I am a new user and would like to know if I need to purchase an account to create different content? 

I wish to add the content type Image Sequencing to the menu list of interactions within an Interactive Video.
I find it a useful task to arrange photos of a scene or of process steps in the correct order, as seen in the video before.
