I think it will be very nice to add justify alignment, so videos will look perfect and more professional.
Hey there. This is something we are looking into. You can vote for this feature here: https://support.powtoon.com/en/article/request-adding-a-snap-to-grid-feature

Yes please, now the alignment takes a lot of time, and sometimes in the end it is still not perfect. Take for example the alignment functionalities in PowerPoint, they are great and easy to use....(sorry for this example :s)
I agree, even with the grid feature, it can be difficult to justify or "snap to grid" different elements.
