I was checking some errors that could be improved in next version. I'd like to post some mistakes and features you could use in next release - just suggesting

1. Error when starts RC: It doesn't maximize at all at startup.
2. Sample directory in config directory: When choosing "Romsets" The directory button doesn't appear when ussing "Split" option.
3. In "Shell" operations, you should include Copy and move to folder, either for romsets or individual files.
4. CHD Reading and checking inside the zip file - I know reading would take some time, specially the big ones, but some are not so huge - Speed experiment can start from here.
5. Personal proporsal: Language translation pack for 3.0
6. Directory error - I've posted before.
Take them into account! I love romcenter due to it's easy interface, precise rom handling and the possibility to reuse roms in different emulators.
Thanks!
