Fixed some problems with the settings not getting applied and remembered correctly.
Changed the numbers on the contrast slider for the RAW settings to try to make it more clear what it does.
Fixed a variety of problems with alignment and composition.
Fixed other minor problems.
Fixed some problems with the settings and having them take effect. In particular, the check box for requesting 32-bit floats was not working reliably. Note that, in general, you do not want to use 32-bit float output. Exceptions are very low noise camera (e.g., Hasselblad at ISO 50) and very large number of images being stacked (over 100). I have tested the 32-bit output with Preview, Photos, Affinity Photo 2, the new Affinity, Photoshop and Lightroom. All except the Adobe apps work exactly as expected. The Adobe apps require some tone curve work to get the tone back to where I expect it to be.
Changed the numbers associated on the contrast slider for RAW settings. It was 0 .. 2. It is now -1 .. 1. I hope this more clearly represents a small reduction to small increase in the contrast. The internal behavior is unchanged. Any changes you have previously made to your settings will be automatically updated to the new numbers.
Fixed some issues with alignment that came up occasionally.
Made an adjustment to how composition works. There was the remote possibility that the composition could add color fringing to high-contrast areas.
Fixed some problems with opening files from the Finder (and likely also from Lightroom and other apps). This used to work, but changes to macOS over the years have changed the way applications are launched and I had to make some changes to adapt to those changes.
Fixed a problem where, at times, it was possible to attempt to save with cmd-S when there was nothing to save. This could happen when processing multiple image sets without quitting.
Fixed a problem with the size of the cursors when erasing stars and painting an alignment mask when the image size is greater than 150M pixels.
