I started using SNAP recently and have figured out how to do many things, but for the life of me I can’t find the “GCP Manager”. I can make GCPs and then call up the table to view their attributes, but I cannot edit that table. I see discussions online about how the GCP Manager is used to do this, but I can’t find a menu item or an icon for the Manager anywhere. I’m using the latest version of SNAP (9.0) with the Sentinel 1 Toolbox. Please let me know where to find it. Thanks!

@Marpet answered your question, but it is worth mentioning the Help Contents can provide answers to such questions. Entering “GCP Manager” the search text box should lead you to the same answer. It is also worth spending a little time looking at the top-level menus to get a general idea of what can be found under each menu entry.
Thanks! I will indeed dig deeper into the basic menus.
