That is a good tip, thanks. But for me it is more a detour than a real “focus-mode” option. Or as they say in the MAC-forum (Focus Mode? - #8 by gusmcgee):
If you have a closer look at the introduction video on iawriter.com (from sec. 35 they introduce focus-mode) you will see the difference between focus-mode and paper width and properly understand the power of a focus mode.
I fully understand that this suggestion is out of place in a beta testing phase, I only want its place on the “nice to have list” because I see it as a advantage during writing on a computer.
The flow-mode is the other suggestion for that list - no cavort around while writing, unbeatable to generate a flow.
Simo.
