Total Commander

I often use double sorting by type and then by date. But usually I need to group some types, e. g. .doc and .docx, .xls and .xlsx, .jpg and .jpeg etc. together and not to see them separately. Is it possible in current versions or can it be implemented in the future?

There is a plugin for that.
