Small sidenote.. I seem to miss alot of documentation for features which are present and work the same as the HTML variant.. But they're not present on the React docs. (for example alot of keenthemes custom scripts like sticky etc..)
Thank you for your message. We are working on documentation right now, we have 2-3 important core releases, after that the documentation will be revised from scratch.
React Demo1 will be revised and published in the next two versions and includes the MultiLayout feature (core and layout updates). Can't give the exact ETA, should be done in 2-3 weeks.
