There's a pretty serious bug in this library that causes the app to crash when hiding the indicator. There have been two PRs to fix this already and you haven't responded to either.
Given that there are obviously people, like myself, depending on this library, I think it's for everyone's betterment you do something to make the state of the project clear to everyone, by either adding another maintainer, starting to respond to PRs, marking it as unmaintained, etc.
