I frequently have to typeset Japanese, Chinese and Arabic, and it's very unfortunate the interfaces for the language tools cannot all be included in the same version.

My understanding is that every version of the software is identical under the hood, and there's a simple hidden parameter that enables the different language tools after a reboot, but it would allow for a much smoother workflow if this could be done within the software. For example, under Workspaces have the option to choose workspaces that use a different language toolset, with a reboot required if necessary. Can this be addressed in a future version?
