My quickly reply. I read all this long debate and the igor_ubuntu's article in his blog about "Batch Render". I think that the problem is How many users use that features? I don't use them but, maybe, somebody yes, as I always said in MantisBT; then you can not decide if delete/hide a function that is used (?) by other users, I think. Would be better that a modal window, with a warning, came out before overwrite a project? Yes. I think that a user can do a test on a short video/project (or create a backup for your own important works) before going on some feature like Batch Rendering, and reading the Manual: many people are doing a lot of work to write it. I would like to know how many people use this and that function, so a developer can make the right thing, if he is not a filmaker/editor. IgorBeg
