First im a big fan of Adobe Spark it keeps getting better. But there is room to improve more.

I already made a video project that is optimized for youtube video. Now I need to make the same project to make it fit instagram story (screen verical). I tried to use the resize function. Instead it made my video project small to make it fit from the sides and it's not stretching it to make it fit the entire screen. So two ways to improve:

1- improve the resize function and make it change dimensions to adapt to the vertical position of the screen without leaving empty unused spaces. This way I dont have to rebuild the entire project from scratch to make it fit another app

2- maybe have a library section where I can transfer elements from one project to another. For example, I made my video project on the computer and all elements are there. Now I'm using the app on the go for convenience. Although I have access to my completed youtube video project from the app, I found that I cant transfer the same elements I used from this project to use on my new instagram story project. So now I have to go back to my pc download all the elements I used to my phone and build it from scratch. Instead it would have been easier and more productive to just transfer elements across projects especially that they are already in another project in adobe spark
