Another small thingie with master volume. When dealing with 10% or less step to increase/decrease is 1%. When going up works fine till 10%, then shifts to 5%. Going down there must be "less or equal" problem. When on 10% and pushing decrease button decreases for 5%. It should only for 1%. Not very annoying as you can reach 9% from 10% with 1 (down for 5) + 4 (up for 4) steps but as it is simple to resolve, why not.
