There is a new version of a keyboard layout for, Telugu. It is located in the Development > Keyboard and Lesson Development course, in Topic 1. Please let me know what you think, if you try it out.
I know that the parenthesis keys, (-shift 9, and )-shift 0, are not implemented yet. Will not seem to type in MooTyper for this layout, just yet, for some strange reason. However, so far as I know, everything else seems to work.
