By the way! Thanks for Treesheets I love how naturally it helps you when thinking through a topic. I built a Python treesheets cts file to HTML converter so I could quickly see my treesheets along side other notes in my notebooks. Issue created: https://github.com/aardappel/treesheets/issues/185 My (partial) parser in Python: https://gist.github.com/quag/e219f69670cd395d4a59a392557df28... If people would like the current format documented and simple test files to parse please let me know. It’s a 1-2 day task to get it to the point were I wouldn’t have had to read the code to write a parser.

Yes, 2K over 10 years, for 15$ a month. Not worth keeping that going, given the expectations.. $100 for a feature does not make sense for me. I am on GitHub Sponsors (https://github.com/aardappel) but really only use that if you feel very strongly about it, since it is never going to compete with my day job. Getting people on patreon etc also requires a lot of "marketing" I don't have time for. There's not a ton of examples of the scripting functionality yet, but here's one: https://github.com/aardappel/treesheets/blob/master/TS/scrip... and the reference (view file locally, sorry): https://github.com/aardappel/treesheets/blob/master/TS/docs/... Beyond that you'd need to check out the language site to learn more on how to use it :)
