Great app, but can use a tune up

At this time, I have all 369 guns and 7,004 skins. However, none of the newer ones under the skins "sort by gun" menu in the gun store have a selection for the new guns. Some older guns (i.e. MTS-255, CZ-805 Bren, Tabuk) still do not have respective skins packages. Please update. It would be interesting to see a skins package for the Panzerfaust and eventually see a Panzerschreck addition to the lineup.
Also, with the lineup including the following:
Glock 17/18/19/30;
AK-47/74, vz.58, wz.88;
RPK/RPD;
Dragunov SVD/SVDS/SVU-A;
when will there be a PKM and PKP added to the platforms in the future? It seems the experimental former-USSR/current Russian firearms are listed like the TKBs and A-91s including the prototype. Those two would be great additions.
