Describe the improvement

As the picture shown, the bottom progress bar now is pretty large.
Can we make the spacing apapting to number of rows?

A minor quality of life UI change.

Thanks for the suggestion. I've merged a PR that implements this, so it will be available in the next release.

I also capped the resize at three operations, so the progress bar doesn't grow excessively large while still adapting to the number of rows.
