When you choose to display a multi-value field as a column in the Web Client and the number of values is more than 1, the Web Client displays a number next to the value noting how many values there are:

I have noticed however that this only goes up to +254. I'm sure there is a reason for the 254 cap, but I would like to request that if there are more than 254 values that the plus sign be moved to the other side of the number, such as 254+ instead of +254.
