It's a minor issue, but sometimes the scrollbars in the Adjust Tag Information are inconsistent. (See attached image). If the suggested titles are many characters long, and the current filenames are short, one list will have a horizontal scrollbar and the other will not. This causes vertical misalignment.
I find this undesirable because it is harder to check that that the lists are of the same length. Even if one scrolls down to the bottom of both lists, the lists are misaligned.
Maybe if one of the lists needs a horizontal scrollbar, both should be given a horizontal scrollbar.
In the attached image, both lists are of the same length, but visually it does not appear so.
