Saw a new topic appear in which the OP used the tag panel at a smaller width previously (with vertical scrollbars) and they wondered if there's a way of restoring the previous layout (at least from what I can glean from translation).
Perhaps a way to reconcile the two concepts would be to always expand fields downward if there's not enough width to expand into a new column (ie: avoiding horizontal scrollbars). Just an idea I figured I'd suggest after seeing that topic.
Not sure how tricky creating such fields that flow to fit the height of the Panel and other columns as necessary would be, while also only expanding downward if there's not enough Mp3Tag window width to add an additional column, but seems like it would suit both workflows. Anyone else care to share further thoughts on this?
Edit:
To illustrate the concept more visually I mocked up some examples in the browser that I took screenshots of, each with a progressively wider Tag Panel. The dark grey bar on the right represents a scrollbar.
There's also the question of how the layout could flow when there's enough width and height to fill:
Either for example:
Same as above but user resizes Tag Panel height to accommodate:
Or alternatively the fields always prioritize height over width when there's enough room:
