This is something which has been often requested in the past, and something I am going to look at. Some early decisions in writing the code for beorg has made this slightly harder than it otherwise would be to support - however something I am very keen to get sorted.
I'm a Beorg premium user and I love it. Unfortunately, during my intense use of Beorg, I've found something that really makes my productivity and workflow worse.
I sync all my org files with Dropbox, but Beorg doesn't show the files in subdirectories (for instance, the file Dropbox/someorgfile.org is visible, but Dropbox/somedirectory/someotherogfile.org is not visible). Is there any trick that could fix this problem?
