Hey you should add the option to change the hotkeys/keyboard shortcuts, you do it and i'll give it 5 stars .
It'll be perfect like that ,because i already have other hotkeys for another software Set on Ctrl + m , Ctrl + < , Ctrl + > - so they interfere :(

Its hard to use. You should implement is as the suggestions in Microsoft IME for Japanese language support where after writing a word you press space and get the suggestions there and can navigate with the keyboard.

Very good!

However, the pop up text suggestions are inconsistent. several times the pop up did not appear when needed. need further development.
