– Go backward using up or left arrow key is already implemented in the upcomming 1.4.0
– Support for international characters is already on the upcomming 1.4.0 (Spanish, Portuguese, Turkish, German, and so on.. but not Arabic, Russian or Chinese characters)
– loop video is on my todo list, but won’t appear in the next version.
– Copy/Paste/Drag and drop objects will be on the 1.4.0 too, but not copy a full slide (But I agree it is needed.)
Anyway, I will work on the remaining issues as soon as possible.
