Isn't there missing a link for SMTube website on SMPlayer website somewhere ?
Also the SMPlayer website says "SMPlayer can play Youtube videos and it also includes a handy tool which allows to search for Youtube videos.".
Maybe it should be "SMPlayer can play YouTube videos and it also includes SMTube, a handy tool to search for YouTube videos.".
But when i install SMPlayer, SMTube is not included. So maybe that should be changed to. I have to download SMtube after installing SMPlayer to use it.
