Max client name len
This option specifies the maximal length of the client names as displayed in the interface. If the client name is longer than max_client_name_len, it is trimmed. Adjust this setting if you encounter line-wrapping on narrow terminals and are not happy with it.
This option is stored in downloads.ini
As of MLdonkey 2.5-28o, this option is not consistently working throughout the application. For instance, it has no effect over client names in GUI||Gui or |TelnetUI, but indeed does work for Web interface.
