For projects with multiple slides, add automation - pan, pan and zoom, fades between, etc. Assigning filters to each one is very time-consuming on multiple slides.
Also, automate assigning transitions between clips without having to overlap clips manually. Have the SC automatically use a few predetermined frames/seconds from clips to create transitions.
At the very least, you should be able to “batch” process multiple clips. Meaning, select all slides, or clips and assign the same effects/filters/transitions. It seems that right now you can Ctrl+click to select multiple clips, but filters get assigned only to the first clip in the selection.
