Custom view (such as rounding)

[Drakuun]

The notation seems currently quite long, goes two digits after the comma taking up unneeded space.
Would be nice if I could round to the KB or the MB whichever is highest.
Also, the unit notation does not need to be a space from the number for me.
If I could have a notation like 90mb instead of 90.15 MB this would save me space so I don't need to expand the minimum tab size by default.
