Should be good if I can choose of the languages of the help. At now, this requires modify the language of LibreOffice, close and start (restart). If I close LibreOffice, the help is closed so. If should be a choosing list, it should be possible viewing help more than 1 language at the same time.
For example, if the language of LibreOffice is X, and help in X is not installed, I can not use the help if I do not have an internet connection, even help is installed in 100 languages so. (Naturally, I installed only 1 help.)
Seems like a good enhancement to me.
By the way, there is no portable help. If I do not have an internet connection, I can not read help when I am using LibreOffice Portable.
The new Help (Browser help) is packaged and distributed in the languages selected.
For help in other languages, the easiest way is let user access localized help in https://help.libreoffice.org and select the desired language in the Languages drop-down menu.
