I think you should be able to further reduce the size of the logs. for a lot of the wood working you need to have the same type of wood and seeing as there are no tree respawns yet, it is very hard to obtain the amounts needed. It would make things easier and not to mention more realistic to be able to chop up long logs into short ones.
also on a side note. we should also be able to carry more than one small log if we can carry an entire tree.
