Feedback after testing

[travishaagen]

Hello! This is a great project and I appreciate your efforts.

Here's some feedback for some things I noticed,

Higher priority:

• If a file is not recognized, the screen goes black, but eventually recovers. I had some .HEIC files and it prints an error to the log (Skipping ... cannot identify image file), so perhaps it should also filter on file extension.
• Noticed random images sometimes being repeated soon after displaying the same image. One time it was immediately.

Lower priority:

• Wonder if the image-pan could be smoothed out. Sometimes it's a bit jumpy.
• I was fine dealing with --skip-setup 0 being the default, but others may struggle with it. May be another way to handle this more automatically.
