Can shotcut edit videos?

I could see how to chop bits off the beginning and end, but how to cut the video in the middle and remove bits? Do we need to export all the bits and then glue them together?

How come Apple iMovie is so easy, but Linux stuff is so hard?

Go to Youtube, type shotcut tutorial, watch videos. You may need to search for beginner tutorials… There are some good ones to help you. Good luck!
