The goal of the long string was to add plus sign for completeness and color code each part to aid readability in a long table, where the headers may be far away on a big screen and there may be multiple numeric columns side by side. Advantage of a rounded/truncated number and precise in the same space (other programs may show the fraction and unit in smaller type, which we can't do). How long the formatting string is doesn't matter that much. I don't see it on the main window, or when I add the column by right-clicking on the header. Even on a playlist of the whole collection there isn't a noticeable pause.

I don't see a big advantage of a built-in tech field for lufs it it can be calculated already. If they add it, fine. You probably can get your request through. Most of us others cannot. That is why I use Foobar that can be customized.

The proposed ('Short') column doesn't show minus sign for RG -17.01 .. -17.99

It errors out on very specific values. Here's amended version that shows ±0.00 for zero, minus even for small minus values and + for positive values:
$if(%replaygain_track_gain%,$puts(l,$num($sub(-1800,$replace(%replaygain_track_gain%,.,)),4))
$ifequal($get(l),0,±0.00,$ifgreater($get(l),0,+$div($get(l),100),-$div($get(l),-100)).$right($get(l),2)) LUFS,)

Though I have no idea if LUFS is supposed to be formatted with plus sign, I couldn't find documentation. I found something claiming 0.00 is max value. Adobe Audition doesn't show plus sign.

Edit: removed unnecessary minus sign.

Plus might not be required. The value looks more distinct that way, as I mentally process normal negative numbers and ignore the minus. Measurement tools appear to be split on this display convention.

No sign: Izotope RX5 (unweighted RMS has plus), dpMeter2, TC LM6n, VisLM2.
Plus sign: Izotope Insight 5, Ozone 5/7, Pro-L2.

Power of Foobar's title formatting allows adding/removing it!

Oops, right, lack of float support. I thought he was scaling the number based on some range. I should have looked closer.
