Thanks for the purchase and your long feedback, really appreciate that!
I have put a lot of time and effort to make Panda 2 as easy as possible for beginners to start game programming and the engine API easy to understand, so it's good to hear those comments.
About the documentation, did you notice that there is also simple game templates for download? (https://www.panda2.io/templates) So there is video tutorials, game templates, playground and API docs. I will keep adding more content on those as much as possible (i already have three more game templates ready and waiting).
I have been thinking about a trial version too, and will think more again. I'm just not sure yet how i would technically accomplish that, how would i build a trial version of the software without having to make a lot of changes to the code or having end up with two separate versions. And what features should the trial version have and what not. But once i figure those out, i will probably make a trial version available for download.
I will update the license to be more clear on that you can use the platform to make commercial games, thanks for that suggestion!
About the editor feedbacks:
By this, do you mean you would like to be able to see the projects list without having to close the current project? Currently you can go back to the projects list by clicking on the Close button, that workflow has been working pretty good for me.
Currently you can switch back to the classes view by clicking on the project name or module name on the top left corner, and also by clicking again to the button that you used to switch to another view on the sidebar, for example if you click on Assets button to switch to assets view, then click on Assets button again to switch back to classes view. I agree that it would be a bit more clear if there was also Classes button, i just tried to save some space and put there as few buttons as possible. But then i also want the ui to be very clear and easy to understand, so maybe i should add that button on the next version.
Again thanks for the feedback and let me know if you have any issues. Also looking forward on your new game projects!
