Yah, now that we have the ability to change font size; and in some cases "word per line" which alters margins or font family; I'm hungry for more.
Is it really so hard to add the control: full justify vs ragged right vs "as shipped"?
Or for spacing between paragraphs: remove a line vs add a line vs "as shipped"?
Or for line spacing: more vs less vs "as shipped"?
Having access to these minor tweaks would go a LONG way to solving almost all the inept, thoughtful or plain bloody-minded formatting that passes for "commercial grade".
And, yes: strictly "on device" tweaks -- I have NO desire to ever even consider touching the actual file under the hood.
