Repeating subtasks & couple other questions

[GiornoAndCleo]

Hello. Thank you very much for the app! Let me ask a couple of questions from an ordinary user.

1. Can you please tell me if there is an option to assign a repeat to sub-tasks? I have not found, unfortunately, how to do it. You can do it for the parent task, but the program does not allow you to do it for subtasks. Or I am missing something due to inattention.
2. Are there any plans to introduce an advanced option to print selected tasks as a regular task list?
3. Is there a possibility to support the development of the app with donations?

I am using licensed version of the application 2.6.6. on Linux Fedora 42 in .Appimage format, if I remember everything correctly.
Thank you in advance for the answer!
