Minor gui issue, the quickfilter categories dont seem to be properly aligned when they are collapsed. Note the scaling space between the items:
Maybe a vertical spacer under all the items would push them up properly.
Now that the dialog has complex filters in there too, by default, you kinda need to make it pretty wide to not look incorrect. So maybe adding tabs for the different quickfilters, instead of the current vertical list might look more manageable.
Or maybe an option to hide the regular filter option there so we can keep that quickfilter window small?
