DropDown for show damage

Hey,

Something I was eager to have from day 1:
When you open the character window ©, going to the 2nd tab:
There you can see damage for the skill on LMB and on RMB.
Well, it is often the case that - for whatever reasons - the skill you´re interested in (main attack skill) is on neither of those.

So just why not converting those 2 damage displays to 2 drop down displays, where you can chose the skill damage to be displayed (1,2,3,…LMB,RMB)?
Yeah I know, there´s ofc a workaround for that. But why? Things could be so easy and convenient.

Thanks,
k.
