 Hi all,I'm currently learning and using the gtpack package, which is a Mathematica based Group Theory Package. However, I also encountered some problems in use, as follows:(A). gtpack can't be reloaded repeatedly, even I've wiped the variables/functions and removed all the symbols from the kernel with the following commands, as commented here:  ClearAll[Evaluate[$Context<>"*"]]; Remove[Evaluate[$Context<>"*"]]; Basically, I mean, if I try to run the following command sequences: << GroupTheory; ClearAll[Evaluate[$Context <> "*"]]; Remove[Evaluate[$Context <> "*"]]; << GroupTheory The following error will be triggered: Error: The axis label x already exists! \$Aborted (B). As we all know, when a user enters a partial string at the beginning of a command, Mathematica can prompt the user for all possible candidate commands. But I can't see this feature for all commands/functions defined in gtpack package. Considering that there are many custom commands and function names in the package, this is very inconvenient for users. Therefore, I wonder if there is any way to achieve this.(C). I've noticed that the complex represention of "SU(2)" matrix corresponding to the same O(3) element, for example, R(2Pi/3, (0,0,1)), has the following two different forms, as shown below:Any hints for these differences and questions will be highly appreciated.Regards

 Have you contacted the authors of the package? They will have the most familiarity with it.
