Filter slider:
The slider for adjusting these filters:
blur
soften
enhanced edges
sharpen
add noise
it's squished between the text and the input box,
currently to use it, the window needs to be resized first.
The slider should probably be moved above or below,
the text and input box
Filter Preview:
When one checks the [checkbox] Preview,
the preview images height are really short.
The filter window should probably be taller when the preview option is checked so that the
preview images have the same width and height.
also it would be nice if the filters and adjustements in the image menu
could be applied to the selected area like it works in xnview.
