We have just finished the first version of the documentation of Document Node and published on the website (https://documentnode.io/overview).
We will update it with each new release, or whenever any issues are spotted.
In this version, we improved the performance of opening file tabs in the editor area and fixed a couple of other bugs. For more information, please see: https://documentnode.io/release-notes/relnotes-1.2.129
Have a nice weekend!
