Duplicates finder issues and improvement

[inkvolcano]

Love your program!

Have some issues with comparing videos.

• video data (resolution, lenght) does not update properly, i only see the first video proper and it does not update when moving on to the next one.
• crashed when undo

My suggestions:
Show more data, such as file size, encoding type etc

• Colorize bigger / smaller for each data so its easier to see which file to keep
• move overflow double files to a folder unstead of removing
• link videos so when you skip, you skip both sides
• add a goto last frame and freeze function

Hope you can implement a few things.
Keep up the amazing work!
