user channels naming

Hi,

Would it be possible to have the renamed user channels show in the export textures windows with its new name?

Currently renaming a user channel in the texture Set Settings panels (for exmaple from user0 to Mask1), is not propagated to the export texture window.
When creating a lot of custom channels it becomes difficult to see which user channel is the right one to use when creating outpust maps.

One side note could If this is not possible could we at least have the user channels listed in numerical order.

Currently it goes like this:
user0
user1
user10

user11....
with user2 being below user15

Thank you.
