Agreed, you cannot believe how much time I “waste” on formatting for the kindle.
I worry about the kindle formatting after I get it back from the editor.
At that point I have to have one format for the Paperback and another one for the kindle and then what looks good on a new kindle is crap on an old kindle and my head spins and I have to submit bug reports to the kindle team because they can’t import some table/line formats properly.
It takes a solid two weeks to get the books through the publishing process at Amazon. First book I did on B&N, Smashwords and Playstore…that took forever.
