Thank you for the feedback. I will try to answer all the questions.
1. When you open a program you don't always want to start from scratch. Maybe you want to open an existing project and opening a project by default is an unnecessary delay in starting. If you are talking about the speed of creating a new project you can use the CTRL+N hotkey which is faster than going through the menu. Also with the advent of settings I think it will be possible to make an option.
2. CTRL + S is already available from the first version. If your hotkeys did not work we would like to know the details.
3. To export you need to have output nodes created. Then you need to select the folder where the program will save the files.
4. Settings are planned after the implementation of patch 0.3 . We apologize for any inconvenience in connection with this.
5. Convenience options which I mentioned in the article just contain these things. We try to make everything as competent as possible and not to run ahead of the locomotive. Thank you for understanding.
