Did you just purchase and install Premiere Elements 14 from Adobe? Or, are you evaluating the free 30 days tryout of the product? By the way, the tryout has the same features as the purchased counterpart. If you have purchased from Adobe, then you can request a return/refund within 14 days of purchase.
If you purchased else, then you are governed by the return/refund policy of the seller.
If you want to continue on the basis that Premiere Elements is what it is and not Vegas or Premiere Pro, I would look forward to the opportunity to be of assistance in answering your specific Premiere Elements workflow questions on its how to. So, that you do not have to invest in books for purchase for a program that you do not want, you should consider going through the free Premiere Elements 14 and Elements Organizer 14 Help PDFs.
After you go through the Help PDF, I will give you fuller description of the Edit area monitor and the Preview Window with its Set In and Set Out points for trimming video. If your other interest is dual monitor, I can talk to you about that. But Premiere Elements dual monitor does have its considerations which may not work for you.
This is not Adobe. Rather essentially a user to user forum. There is an opportunity to file an Adobe Feature Request Bug Report Form.
Please consider. I am willing to share Premiere Elements principles and features descriptions with you if that is of interest.
