This is an Electron JS based application. When given a directory containing a bunch of images it will display two of them, at random, side by side. There are some keyboard commands that let you change the images ...
- E changes the right hand image
- Q changes the left
- W changes both
- - reduces the margins
- =/+ increases the margins
If an image pairing appears and you particularly like it you can press
- P to save save it to list of favourites
You can scroll down to see the currently selected favourite parings. Each one will have a 'Remove' button next to it to remove it from the list. The list is automatically saved in the images directory as a file called 'faves.json' so that when you restart the app you can review all the parings already saved.
I think that's about it.
