I think that these are great features; however, I think the main problem is that this is called version 2.0, if it were Simplify Music Pro or something like that, I wouldnt have a problem as it would be clear that this is a different version of the software.
Unfortunately this is being called version 2.0, therefore it is an upgrade and from what I understand of the terms of service, upgrades for applications on the iphone are supposed to be free per Apples TOS.
So, is this version 2.0 (aka an upgrade) or is this a new, more sophisticated PRO version?
For the record, I got my original one for free and considering the amount that I use this product, I dont mind paying for it, to support the Developer, but if I have to keep paying for upgrades. then there will be a major problem.
The only other feature I could see creating a new product for (and legitimately being able to charge as a result) is Simplify Music & Video
