awesome! It would be also nice having specific releases to be pointed by go modules. Are you planning also having support for selenium4?

@rmescandon , I just pushed new tag - v0.9.10
Current plan is to close gap in features that exists in other implementations, next would be have real browser test automation reimplemented and next focus on selenium v4.
As of now Selenium V4 is added here - #15, but it wasn't tested yet.
