RTL / LTR Toggle for Posts

[Soultrape]

Hello there

I was wondering if it'd be possible to make a modification, so when posting, it'd be possible to align the written text from Right to Left / Left to Right (Both in editing time, and when viewed)

Thanks!

I only mean that a toggle that'd add a style="direction: rtl" :-/
Can't be that hard to make :<

Cheers
