Few issues need you your help

Hi
Kindly advise me on the first issue and assist on the rest of challenges.
1. Is it possible to run an update and retain some earlier adjustments on the plugin?
2. Please help on how to truncate titles on the lesson navigation. I mean the ones next to Prev. and Next
3. To create a redirect page for sign-up for protected content. Currently, after the preview lessons, the next button is inactive. I would love it to redirect to a page giving the user option to buy the full course.
4. Please sort the menu pop-up page on mobile view. The pop-up covers the course. Please enable an auto retract after a user selects a lesson.

Thanks in advance.
