I'm using Mavericks with no intention of upgrading and everything's fine except iPhoto. I really hate iPhoto. I've looked through plenty of the "best iPhoto replacements" and none ever explicitly mention the ability to choose a custom order for displaying photos. I don't have time to try every one that has a trial - and some don't even have a trial - so I wanted to see if anyone already knew an app, by chance. I'm looking for an app that displays local photos in a clean, gridded GUI, but allows me to sort them in any order I choose without having to modify metadata etc. (like how in 10.10's Photos.app, one can simply drag photos to reorganize them in the grid). Hopefully one actually exists because other methods of custom sorting can be incredibly time consuming.
