Dangerous section

Unsafe GUI in batchrender
  It serves to hide the button Save to EDL Path present in the Batch Render window. In fact if used accidentally, it could lead to the loss of the original EDL content, which is overwritten without changing the project name. See Batch Rendering, section Advanced features.
Autosave continuous backups
  For each editing action CINELERRA-GG creates an automatic backup. To avoid excessive creation, this option limits their number to 50 when quitting out of the program.
