I have a custom source called "Samsung TV+" and I simply would like to rename it to remove the "+" symbol.
I was hoping to be able to do it when opening the "Edit Settings" menu for this source but the "Nickname" field is greyed out and cannot be changed.
So it seems that I have to recreate the source with a different name and copy/paste the content.
Not the most complicated thing to do but renaming would be so much simpler. 
I'm guessing that renaming an existing source probably is not as easy as it seems or it would be offered as an option already.
I thought I would request it anyway.
