Please note, I also started 1986, since 1990 with Unix/PC/Ingres and we develop also since Delphi 1 for the financal market, key projects for customers who manage up to over 1.000.000.000 €. So, not only you, also others did not get the time for "test and play".
And sorry, "developing components" is not "playing" - it's a chance to be better and win in the market. BTW, to extend components by existing - often not more than a few lines of code.
To my mind the thread should not drift down to a level "oh oh, 800 €, 1000 €, how expensive ! we can't pay" and on the other side "we will not be able to use unigui if not all features for our projects can be done by simple: click,click".
All of us will be able to save much money in development and Farshad shall be the only one to do the work for, providing a complete development tool with all features ? For "perfect results" - and that in advance ? Still not earning money ? - Please be patient; permanently ask for new features - that's really not fair to him (Sorry).
Isn't it time for an official release of unigui without more features, but "as it is" ?
