Excellent app at what it does, with a few small issues

First of all congratulations for what is a very good app (ImageMini). I have some issues though that I think you should address:

1. Why does the app start processing files as soon as I add them? If I change the export size it will cancel the images that have already been processed, and only do them again at the end. I think this approach is wrong - the app should not do anything when files are added, but rather when you export.

2. When exporting, there should be an option to overwrite originals. This would save me the time of having to manually replace the originals file - if I want to.

3. The export size parameters (width x height) are not respected correctly for portrait images. Consider the following example:
- original size: 5184 x 3456
- export size chosen: 2048 x 1536
If the image is in landscape mode, the resized image is indeed 2048 x 1536. But if the image is in portrait mode, it will use 1024 x 1536, which I think is wrong - it should rather use 1536 x 2048 (the reverse of the export size I chose). This way all images will have the same dimensions and correct orientation.
