Using the trial version: Apart from the 'slightly above' or 'slightly below' radio button settings in 'Extra features' I can't see a way of adjusting the vertical position of the line in relation to the mouse pointer - e.g. to drop it a little more. Is this an option which is available in the paid-for version?

The functionality you mention is not yet implemented. Thanks for the suggestion, I've added it to be implemented in the next version.

Thanks, it would be really useful as I find that the current line position can obscure the text I am trying to read when I have the cursor at the right height to click to insert (particularly important when proof-reading!)
