Thanks for the info. Consider that in the last built (cinelerra-5.1-ub16.04:static built dated Feb13 2019) I see the three foundamental mode with LMB, MMB, RMB are inusable for me. I don't know as others users can works without them. When i drag an edge with Shift+*MB in Program's Timeline (arrow left or right showed) the split view in Compositor always shows two views, side by side, of the left clip in the timeline, never the left clip on the side left of the Compositor and the right clip on the side right of the Compositor.
As you know, I am still using the very good and stable Cin-GG built dated 21081231.
Thanks.

We have come up with a plan to allow for usage of the older Ripple methodology too.

Has not been coded in yet though. Will let you know soon. gg/Phyllis
