In the event someone finds this thread before cherrytree is ported to C++, you can still have cherrytree on tumbleweed so your existing notes are not stranded.

You need two things

  • cherrytree
  • python-gtksourceview


both are available from suse download for tumbleweed under the community/experimental.

(The spell check will not work you need the very outdated "
python-enchant")
