1) Switches like -at, -c, and -tg support +value to add to the existing list.
Please add support for -value as well.
2) When a category in the -c switch matches an existing category, except for the case, it replaces the existing category.
Example:
-c test
That replaces category "Test".
The above is recognized/documented behaviour, but it could be undesirable.
When a match is found, please do not replace an existing category. Perhaps this can be a preference?
Thanks!
