Hello Timo, this is an excellent library that I'm using with great pleasure, maybe I could contribute (for example, I'd like to remove the calls to alert('xyz') for a custom global logging/error reporting mechanism, that could be console.log, this is because alert() interferes a lot with the user interface, and the developer (user of the library) cannot customize how he wants to display/handle the errors) but I feel SourceForge is really unfriendly in terms of source-code version managing, issues,...
