I'm not a professional designer, I'm a teacher

Í really appreciate the opportunity to use this resourse, but with the new interface it's grown a turchure, I regret my students and I are used to this kind of activities by now. I shouldn't have started using it in the first hand. Now I need to remake my pages 2-3 times and they still come out looking unprofessional and uncomfortable to use. I need to use the fraes of uncomfortable sizes and shapes, which means I have to forsee it while creating the background, which is a designer skill, but i'm not a designer. Since a month this recorce has been brining me to a lot of procrastination as I really don't feel like starting each new worksheet. 

the only thing I'm thinking of now is how to arrange same kind of activities without this resource. As I never get any replyes from here, I'm just messaging this on the spur of the moment. I've just completed a worksheet and it took me 1, 5 hour, with the old interface it would've been 20 mins. I'm so dissapointed that i just cannot keep it. At the same time i have not even slightest hope that the admins will read it and try to fix something.
