Sorry for the missing....I'll answer all the questions in one message! It's more clear!

First of all, thanks for the translations!

Renaming and moving groups, sub-groups, items and details are in the roadmap. This is not possible now because I was trying to use context menus, but it is too hard, so I abandoned that approach.

The program was not made to stay always opened, so I don't thought in a lock system, but it's possible to do.

The file is not the cause of the error! It's another problem. It is the first thing I'll see.

In fact, I forgot to test the import using accented characters. I thought that Python would take care itself of it, without any intervention....but I was wrong!

The source files aren't in the garage (yet). I'd read sometime ago about the process...will try again after fix these issues!

Thanks again for all!
