Honestly, I have nothing to say for my defense!
I wrote this plugin at the request of several users, but I know it's a big risk of problems. It's why I have refused until now to let the user modify the cells start and end addresses directly from the cell table editor, and that I have finally implemented this function as a plugin only, with some severe limitations, such as the cut at a nav pack only, and the ability to cut only the beginning or the end of the PGC.
But I want to improve the plugin so that it is as safe as possible. Since I'm not a VOB expert, I rely on this discussion to find the best solution.
BTW, the user that has reported the problems is Tobi, and I'm sure he read this forum.
