Thank you for your kind words. Glad to hear you are enjoying it. Please post some results in the Finished Creations section when ready. We love seeing the results of everyone’s hard work.
Not currently, but it is planned to happen in the next release or two.
To be clear, the changes you make to an image are saved with the project. As for quickly applying settings to another image, these settings are not persistent at this point, you are correct. Additionally, there are no Copy/Paste controls in that UI either as you can see at this point. The system-wide Copy and Paste provided by your OS works but understand this is not ideal. I will make a note for the dev team to evaluate supporting this use-case.
