An easy way to handle it would be to read down the list and overwrite previous answers with others set at the bottom megapixels can just dynamically merge in your config with the default one with ours at the bottom which will result in ours overwriting the original values.
Can confirm on manjaro phosh dev on version 1.3.0
I don’t think asking for elevated permissions is the right way to do it as that has even more security risks as megapixels will then be running as root and has full control of everything.
I am creating a postprocess script here https://github.com/luigi311/megapixels_postprocess that does image stacking to reduce the noise tremendously but occasionally it fails due to image 0 on the burst being corrupt either showing a completely black screen or a partial screen.
Im running manjaro phosh dev build with megapixels 1.3.0 and it looks like it has a memory leak. Leaving the megapixels app open and monitoring the memory usage with htop shows the memory usage continue to climb until i run out of memory and goes back to normal once i kill megapixels.
