LifterLMS Version 3.13.0

The “Course Outline” metabox found on the admin panel when editing any LifterLMS course has been savagely beaten. We stole its lunch money and we put it towards the construction of an all interface
Asynchronous loading: fixes issues where very large courses would drastically slow and possibly even time out the loading of the course edit screen
Course outline is now collapsible and expandable. This Fixes issues where it was very hard to move lessons and sections around on very large courses
In addition to the familiar (and now improved) drag and drop functionality, you may now also move sections and lessons up and down with button clicks. You can also move lessons between sections with button clicks
Add new lessons and sections with a click or drag a new lesson or section into the existing course
Edit section and lesson titles faster with inline title editing. No more modals with a potentially slow ajax load to update a title. Click the title, change it, and exit the field to automatically save!
Delete sections and lessons with the click of a button
Quick links to view (frontend) and edit (backend) lessons
Completely internationalized. Thanks for you patience translators!
