Thank you Hindie.
You can double click to enter a word.
Single clicking on the word displays a definition.
Clicking in the 'insert' icon to the left of the predicted word should insert it with a single click.
We will look at this again to see if we can make it easier.
We need to change the UI so that the prediction window appears on top, and remembers its position, and if you had it switched on the last time you were writing.
Thank you for this feedback. It is really helpful.
