I'm trying 0.21, I like it very much.
1. the poseidon looks like eclipse, I don't know how many developer likes it, I hope the shortcuts can have an option set of eclipse stype.
2. the now .d extention is provided for new file name, it should be assumed to d file.
3. the new file encoding should be UTF-8 for i18n problems, or have a default encoding option for file/project/IDE
4. if the debug option was choosed for build option, only the main file was comipled, files in other module was ignored without any error.
5. code assist window don't popup after "."

anyway, Poseidon DO great help for me, nice work~
