I created my own category where I could keep all the block that I created together
However, when I "Export Summary" my blocks do not appear in the summary. I was able to work around this by relabeling my blocks as a preexisting category, but it is annoying.
Oh, it's been fixed for a while in the development branch. Since that is still heavily under construction we're not yet decided on when we'll release the next version. But you can already try it and let me know if you encounter any more issues with creating summaries. Thanks!
