[FEAT] use automatic size unit

Is it possible to add a tickbox in settings to change files size appearance in columns to show size units automatically? eg: instead of :

filename | size    | size compressed
01.txt   | 523 317 | 501 608

we'd get:

filename | size    | size compressed
01.txt   | 511 Kb  | 489 Kb

change should only be visual imo so column sorting could still work

Thanks.
