Ever wanted to use this as a desktop app? Well, now you can!

Please note that this is very much a beta release so things may or may not work quite as expected, but everything
should work.
Binaries are available for Windows, Mac and Linux.
If macOS blocks the app because of security reasons (not a bad thing for it to do, ultimately), you can work around that by clicking on the app while holding the CTRL key down and then choosing "Open" from the menu. That will bring up a slightly different version of the security screen with an option to actually open the app. I
think you only have to do that CTRL-click thing once per app.
Note that you will also need to have a working installation of
ImageMagick for full functionality.
