Works quite well except for one issue. If you move the cursor to the end of a word and start backspacing, predit gets correctly enabled and shows word choices. The problem is when you select one (or press the space) bar, an additional space gets inserted after the word, leaving you with a double space.

Example:
"Hello brother and sister."

move cursor to end of brother
start backspacing until only "bro" is left. Then type a "t". Now select "brother" from word ribbon and you are left with:

"Hello brother and sister."

I think the fix would be to only auto insert the space if you detect we are at end of the line if that is possible?
