Best app so far for quickly revewing photos before uploading

I use Xee3 to scan through my photos before uploading them to SmugMug or Flickr. I love how fast and versatile the app is, without the heavy weight of Lightroom and Aperture (useful if you are going to retouch photos, but too much overhead for just reviewing photos and removing duds).

Feature requests:
- Love using the SHARE functionality when I come across a good image, but the Hand Off thru Yosemite to OSX8.1 SMS means you can’t share or delete until the transaction complete.
- Love the Delete button, but can you add a move, label or show in finder functionality so I can review a folder full of images and pull out images that I don’t want without having to leave Xee.
- Love the Magic Trackpad support for flipping thru images. Can you also add arrow key support?
- Allow for the ability to set labels and other meta data tags to let folks tag and sort images
- Often I want to compare two photos and flag which one is best, be a cool feature to allow side by side or onion skinning compare

Keep up the great work on making this my go to photo viewer and slideshow app.
