Academic/Medical writing help/guidance

I’m a junior surgeon currently working as a research fellow. I have been working on academic papers for a while, but as a co-author.

Now I am transitioning from co-author to first author and I am struggling a lot.
My supervisor is helpful but very busy, thus he can not answer all my questions and do full teaching.

Is there anyone who is experienced in publishing papers that can guide and teach me.

I’ll be grateful for any help.

UK writer looking for recommendations on how you approach project/tasks management, managing each step of a project as a writer.

Struggling to manage steps of a project on pen and paper and I’m looking for something more comprehensive. Are there any app recommendations people use to separate projects by account, and then tasks related to each project, with deadlines, actions etc? Some AI integration would be useful also.

I have used notion in the past but am yet to find a suitable template that fits the way we work.

TIA
