An idea to keep the Speed column a little more compact

Describe the solution you'd like

Cutover from KiB/s to MiB/ (etc) before going into 4 digit numbers.

Right now: cutover point ticks over from 1023KiB/s -> 1MiB/s
Alternative: cutover point from 999KiB/s -> 0,99MiB/s

Additional context

This is a little nit picky but it just occurred to me and figured why not. Based on my preference on keeping things as compact as possible without losing information.

I've come to realize this could be a modification for all columns containing file sizes / traffic / etc as well.
