@antix, no problem I see your point as a end-user and I understand your frustation.
The fact we either are too few developers to manage Gideros or each of us doesn't have enough spare time to do all the required work. We contribute to Gideros mostly for free (or totally for free except for Kickstarter), but we otherwise need to earn our living from regular jobs. I somehow manage to work on gideros on my job-time, at least partly, and only if I can prove that the work I do for Gideros is in fact needed for my company's projects. I frequently contribute things not strictly needed though, and try to help all of you as much as I can because I love the tool, and all in all people on this forum really deserve it.
@simwhi is right, building gideros and plugins should be better documented. I am not even capable to fully build Gideros myself yet, but slowly I manage to build more and more parts, and eventually I'll be able to build it all soon.
Lastly, I finally started to work on a game, with Gideros of course, and it will display ads for monetization, so I'll finally have a chance to better look at ads,iab,iap stuff and put my two cents on that matter too
