It seems to work well and output good quality. The only things I'd suggest would be to:1) Enable trackpad pinch zooming and 2 finger panning2) Allow to save in place (same name and format)

I have a lot of images of posters and wanted to adjust them so that the poster would be properly rectangular. It's an odd little task and I figured would be a pain - but this little tool just made it simple. Works just like you would want it to work, and is VERY easy to use - I'm delighted with it!If I can make one suggestion to the developer - it opens in a automatic mode. I then always had to click to go to manual mode. Instead of the switcher buttons, maybe make the automatic selection as a starting point and then just be in manual mode for adjustment? It would essentially work the same way but with less clicking.And I would love to set the default export options - as is, I had to export and then rechoose the format each time. And I would also love to be able to save JPEGs in a medium quality level for smaller file sizes!But those are nitpicks - I am very glad to have found this tool!

This is a warning that this version of the program crops the photo at the guide lines that you insert. You need the Pro version to effectively do perspective correction on photos of buildings etc. without losing portions of your photo. This is not made clear and there doesn't appear to be an upgrade path to Pro without buying it outright. I didn’t even know there was a Pro version when I bought this one.

Is it difficult to make it work with photos app?Feature request:Open photo from Photos app, save back to photos.Thanks
