Multiple Videos/Split Screen

Hi Community,

got Premiere Rush lately in my photography plan and thought I'd give it the chance to replace the good old OpenShot Video Editor I used to tinker all the homemade videos of my choir fellows for Christmas this year, but I'm a bit lost (although I already watched some of the tutorials and read stuff I googled):

- How to fit 9 videos 3x3 easily (OpenShot can do that by itself)?

- Is there something like a property window somewhere allowing to adjust the parameters of the selected video directly?

Thanks
