I believe that I am not the first who speaks about it, but your luck is in front of you! All you need to do is learn how to learn from your market vendors. Before you all that lacking in your product on your hand! Buy abgreads that you need and let the dolphin will be immediately valuable, not only after another $ 500 bought extra features. Moreover many of them are not worth what sellers want for them but people have to go for a compromise. Why do ordinary freelancers can afford to do the right see more module? Why is a group of developers can not cope with this problem? You just have to see the statistics of what applications are best to buy and make their own exactly the same. It's certainly not ethical with respect to the developers. But they have everything in life is relative. Any good for someone else evil and evil for someone else any good! So says the Eastern philosophy) And I agree with it. Your luck is in your hands, you only need it not to reject ) I feel that many users think like me, they dont want to buy something that have to be in start installation.
I will not list the required modules, statistics say it's better than me)
Peace, love and many thanks for a dream that anyway comes true !
