Does Thai have a nice snappy phrase in common usage similar to 'so far so good'? The best I've come up with is จนถึงตอนนี้ ทุกอย่างก็ดี ไม่มีปัญหา, not very snappy and I have no idea how common it is.

I would say เรื่อยๆ which means nothing has changed/ I have always been fine.

Thanks for the suggestion. It's definitely snappy but does it have the meaning of everything being fine up to now but maybe some uncertainty about the future?

ก็ดี ยังไม่มีปัญหาอะไร

How about ยังดีอยู่ (yang dee yoo)?
