Hi Christian Surieux,
A separate list with browser issues will definitely be helpful for some customers.
As a vendor with excellent reputation in cross-browser support, we always strive to fix any browser compatibility issues immediately after we find them or any customer reports them. We are very proud to be a market leader in cross-browser compatibility and we ensure that everything depending on our code-base is OK. Of course there are some browser peculiarities and sometimes certain features can not be supported on specific browsers. In these cases we note that in the documentation and online demos.
