Why do you think so many people who own the library are disappointed/complaining if the library doesn’t have some fundamental flaws?
I just think as I already pointed out several times, that just a couple hours after finishing the last download seem to me much to early to pretend, to know all about the right setup, settings, handling, and usage of every possihble option to be able to judge it's limits. I simply do not want to judge anything before trying hard, to get what I want in real project contexts.
I do have the imnpression that the most important difference between constructive critic and complains and ranting is the ability to become concrete in every necessary detail. And yes I believe you must have tried and explored all settings and reasonable combinations in realproject context, to be ready for conrete and constructive improvement suggestions.
I fear often more or less ranting complains are based on a often nearly irrational idealistic demand of what a product should be.
To be realistic one should better start, from what a product can be. If you know any better product - go for it no problem. If you have any concrete suggestions for improvements let us know but just complaining "buhuhu it is not ideal enough for me" tires me really.
As I said I am currently still a good part away from concerns about how useful which single function is, since I still prepare some ambitious projects to explore it.. And of course I will give my feedback about what my impression is to work with. But somehow I simply have the impression, that complaining a product just a few moments after finishing the download seem to be in grerat danger to be simply superficial.
