You can create a template to do this. Swipe up on the blue capture button and tap Manage Templates. In the template you can set the file you want the new entry added to, and the headline hierarchy so that for you your new entry would be added underneath Inbox. Check out https://beorg.app/manual/#templates in the beorg manual for an introduction to creating templates.

I like my org hierarchy to be
* Inbox
** Thing 1
note1
** Thing2
note2
etc. Note there is a single 1-star headline. How do I do this in beorg? Every time I create a new note in beorg it forces me to add a Headline, and that headline becomes another 1-star headline, but I'd like to file new notes under `Inbox` instead.
