Hi, I'm a user about Goodnotes since 2018.
I suggest a few things to improve the Goodnotes.
This writing was written including opinions of Goodnotes users around me.

First, syncs of the Recording function and Text Box
When I record and write at the same time, the writing syncs with the time of the recording. But it doesn't work in text box mode.
So I recommend you to syncronize the time of the text coming out and the recorded audio.

Second, Recording search function
I would like to be able to hear the recording of that part when I touch the text(or handwriting) in the recording function.

Third, Improve text-related function
Goodnotes have a only one text function. The Text Box function.
It is useful, but it's inconvenient when I mainly use text in notes.
I think it would be better to add extra text mode that may function like notepad in Windows.

Thank you for reading. I hope that my writing is useful for users and Goodnotes.
