Looks like a decent way to fix these issues.
Thank you and yes I always accept PR's that are properly handled.

Ok, great, you're welcome.

I'll watch out for a release, so I can stop using my fork in my app.

you can use the main git now since its merged. But if you see or Feel something needs to be fixed and have a potential solution to it always feel free to submit a PR for it. I do go through and review all the changes before i accept any of them.
