1. When I create new file by writing some data or generate data and save file, then I can load it by "file > open previous" menu, but only that file (and not by file > open).
2. I found workaround to open file(s) in okteta by start okteta in terminal and as argument to it place filename (with eventual path to file). That way it can be opened multiple files, all at once.
So it looks like File > Open command is not working at all (dead option), but actually okteta can open files. That solution satisfy me, so I mark thread as solved.
