Thanks for the replies everyone. See below.
Wow, was it really that long ago for TB 6.1? It’s the latest one I have as to be honest I never liked the new UI / split screen after using the old style for so many years. Have tried many times to like it or at least get used to it. Reason I am coming back again now is because I find TB so good a fit for how I think plus I have two large scale book projects to collaborate on and TB is so so good for this stuff.
The main reason why I was asking about the removal of the tab bar is simply visual inertia I guess, combined with I always use laptop so screen space is important as I do maybe 70 percent of my tinderbox work in map view.
Guess I will have to try to get used to it, yes I know it has the link park, but for me not having that always on screen and in the same place is no big deal.
– As an aside but (to me) related question. Is there any product that will enable sharing a TB map or outline (with notes) easily with a non computer wiz running windows?
