I have used the latest version of pyResMan for some time. And now here are some suggestions. That is just what I think!

S1: You can re-plan the tool's layout, since I think that the tools' layout is not clear and convenient to use.
S2: That will be better if I can copy the APDU records in the list.
S3: When I send the .scr file, there isn't any send/receive records shown in the interface. So show the APDU transceiver record.
S4: Add some proprietary instructions, such as select card manager,delete pkg and so on.
I believe that this tool will be more and more better!
