The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

When trying to merge multiple videos and the you just try to remove the "-merged-[numbers]" part of the output name if you attempt to merge it will overwrite the video file with that same name to an unusable video (with seemingly no way to undo this and get the original file back).

Some kind of warning to inform the user or preventing the user from overwriting a targeted file in a merge seems like it would be valuable for preventing this happening to anyone in the future.
