What I did: Created a note, added short text, formatted some headings, doubled-clicked bar to shrink note.
What happened: When note was reopened, formating had disappeared.
What I expected: That not to happen. Formatting seems to stay in place if I click on something else beforehand. So seems like if you collapse a note immediately after adding formatting, the formatting may be lost.
Things that might be helpful to know (Agenda version, OS and model, etc): Mac, Agenda 1.1
