Show commission but hide "edit field"

Issue Summary

Hi,

First, I wanna say that this module is Great ! Thanx a lot !

Here is my request :

• I wanna show to the sellers what they are expecting to be paid in live
• I don't wanna them to be able to edit the commission rate (sounds obvious)

But the only option I have is to hide the "Commission Field" by checking the box "Automatically calculate commission" (autocalc).

It would be nice to have a dynamic field show only the commission they'll be paid.

I guess this needs to be done with Java, may be in the theme, but I have no idea on how to make it.

A solution or a some help on how to find a javascript for this would be great !

Thanx
