Missing Raw file support

I bought this app to replace the Preview App that came with my new Mac Book Pro. Preview won’t let me simply go to the next image in a folder. I’ve used a windows program- Irfanview for years and miss it on the Mac. If this Image Viewer App offered Raw support, I’d give it a 5 star rating. I am a photographer and I like to simply browse through a folder of images, without opening Lightroom or Photoshop. I shoot in Raw format, but this Image Viewer won’t support Raw images. It’s easy enough to convert them to jpegs for browsing. But, it took a web search to figure out how to make it my default image viewer for the jpegs! Coming from a PC, I had no idea you click Get Info to change a default browser- but that’s my issue, not this Apps.
