Very Disappointing, waste of my money

I had purchased the earlier version of the app but they stopped supporting it so I had to pay for it again to download it to my iPad Air. It was expensive enough the first time and to pay for it again was such an unfortunate waste. I had hoped they had improved upon it, most critically adding cut and paste support. Unfortunately no, they had only reissued it due to a digital signature snafu with Apple that caused my version to be obsolete. In fact they had hardly changed the app at all, mostly just to add the phrase "Limited Edition" to the app. Very disappointing.
