@Cobalt I have used extensibly and I highly recommend. I'm using the the development version though 1.5.1 (the most stable version of these bleeding edge btanch, they are already onto the 1.5.4 but the official stable version is 1.4.7). In all honesty the features and the bug fixes outweigh some of the instability that might arrise. Nevertheless and if you are a fellow cartoonist you might want to give #Laidout a try (I never used it), it was created by a cartoonist/dev!
