When there's no response from me for a while

My notification is flooding and I often overlook your email, ping, review request, etc. When I don't respond for more than a week, feel free to ping me again or open an issue here, I'll prioritize it.


Thanks you for all my sponsors!

You can support me via GitHub Sponsors:

Why do I need your help?

Currently my life is unstable as I cannot work as much as I'd like due to the mental condition/disorder, so your help is definitely helpful to continue my FLOSS journey.

But the donation isn't the only way to support me. You can use/star the projects that I'm involved in, follow my GitHub account, and do various things related to my contributions. It will motivate me in my future contributions.
