Translation of OP:
I paid nothing for some Free software and demand that its main developers add some features instead of doing it myself or paying someone else to do so.
The features are available to anyone interested and skilled enough to add them, and others in this thread have posted reasonable reasons for rejecting those features in the reference client at this time.
If you can apply the patches for those features and then build it yourself, why don't you? Otherwise, you can hire somebody else who can, so why don't you? Complaining in this thread won't change the valid reasons for excluding the features from the reference client.
