if /line need to place 2 point, this one only placed 1 point
example : /line 5 whiteWool
hard for me to explain, i will use this pic

it's annoying that i must make line 67 blocks long but can't make a instant line that have 67 blocks long
maybe add angles will make it more useful
like.. /line [blocks] [angle]
hmm... line+measure = /linem anyone?
i'm sorry if this suggestion already taken or the command already exist, i not really know some new fcraft commands
My english is not pretty good, it's hard for me to explain this stuff :/
