Doesn't seem to be possible. I agree that this would be a good change for the programmers to make.
Hi, There is no way to resize the header at the moment, but we will add it to our list of possible changes to make in the future. In the meantime the only workaround is to hover over the shortened entity name, which should give you a popover of the full name. Jess
I just figured out the hover work-around. But being able to glance at the header and actually understand the span of events in relation to all of their entities… it's critical.
Also: being able to resize most things would be good. In this one way, Aeon is not very Mac-like. I need to control my workspace.
