not really important, but load a cxr file to vfb will be really helpful if I do render selected to fix some material and forgot to uncheck the “clear VFB in between render” and without having render history too.. 
i know I can do it in some external program like PS,but I am a man who like to do a work in one program as long as it is possible.
note: my friend told me that it is possible with vfb+/vray/maxwell which currently I don’t have even 1 of them.
AFAIK VFB+ is free now, so at least you can try it :] Nevertheless, i fully support your request about loading CXR into CVFB. We almost have it with the resume from file option, it just need to be slightly refined.
a bit off topic, vfb+ is discontinued o_O how could i miss it (where have i been?)..? but yes i just saw it in cgChannel, it is already discontinued since February but, seeing a tiny software development die always makes me sad somehow.
and thanks, nice to know that I’m not alone here
+1 for this
