If the author is lurking here, are you doing all by yourself? Do you use any LLM/agent?
It really is impressive.
Yup, this is 97% just me hacking away in vscode -- I use pylance and the debugger but have everything else disabled, easier to focus that way. The only time I use any sort of AI/LLM is for translating new strings into Chinese, since it seems decently capable at that :-)
The remaining 2% is friends coming up with new usecases/features, and sometimes finding bugs.
But now that the project got way more attention than I'd anticipated, pullrequests have started appearing, so it doesn't look like those statistics will stay true for much longer! Really cool having more eyes on it spotting the things I overlooked, really enjoying that.
