Please can you add 'You are leaving this page' dialogue box to Wordpress Plugin
I do a LOT of H5P work in Wordpress, and it's amazing.
However the biggest issue is that - if I accidentally click a link in the WP menu to the left, for example - the H5P editor page will navigate to there, with no warning about a loss of work. When you're 15 slides deep in to a Course Presentation, this can be very, VERY annoying!
I have trained myself to save regularly but a simple pop-up warning to say work will be lost would be invaluable. Could this happen purrrllllese?
