Just couple things with the FITS viewer that have been bothering me, but never enough to post about.
1) switching to log view and hitting apply changes the image. Most of the time, the image just goes completely white. My understanding is this should change the view of the histogram, not the actual image itself?
2) It would be nice of the histogram to save the settings. I almost always use the log view, so it would be handy to be able to default it to that. If I don't close the histogram window, the next image will display in log format, which works, but the histogram itself will get corrupt after doing this 2 or 3 times and need to be restarted anyway.
This is Fedora Linux with Build: 2017-11-14T11:41:39Z but it has been doing these things for a long time.
The histogram stuff are _very_ basic. I wish I had more time to work on it. It would be nice to see histogram on all images by default like in some small dockable window at the bottom left/right of the image... but alas very little time to do that at the moment.
Yes I agree this is a problem. The hystogram view to get the exposure right. Also, both linear and log view are quite different from the in-camera histogram. I think this is an important feature to get right.
