I never applied any style to OF1 for years and when I did I spent ages playing with them until I arrived at what I have now. I didn’t find that switching between them made using the system any easier, its was just aesthetics. Not having the ability to tinker endlessly for me is welcome. For me, I add. However …
the ‘one’ thing that was present in pretty much every theme was the use of a style to indicate functional meaning in the hierarchy such as grouped, blocked, next action and so on. I miss this aspect of OF1 as the current information obtained from the layout itself seems to only be:
Presence or absence of a note
I think that’s it. This seems a step back to me, especially that as the filter bar has gone it’s not possible to know what you are looking at when viewing a layout when all you have is pale grey for every project/action item.
