After testing lumens thoroughly, fixing some bugs and adding several fatures, it finally seems to be ready for a first big release.
Even though Lumens should work as expected and was tested on many devices with many different browsers/version, please note, that lumens has not had the chance to get many practical experience, so there will probably be combinations of settings I didn't consider during testing and which might mess with the slider.
I will gladly look into such cases if you can tell me how they occured.
If you have feature requests, feel free to drop me a comment.
Important
Make sure to use the compiled version, since the uncompiled version is written in ES6 and will not gurantee working with all the tested browsers.
