Like the cycle UI!
Nothing against to make it official one day.
Cycle has a better UI… i hope it’ll be the official one sooner.
I prefer cycles UI, definitely.
AFAIK there was a comit to allow for the old method of splitting the window prior to the release of 2.57 .
As for the + sign its there try hovering the mouse.
With the old split method we could eliminate those triangles. I’m ok with the new 1 click split method, but I’m very aware I’m in the minority and I also would start using the old method if it’s brought back.
Tab headers are way better. Headers stand out. I really appreciate it.
With the old split method we could eliminate those triangles.
Hell no. I love the new triangle splitting, as I find it way quicker!
We have both methods working, and be happy with it 
The old window split method is back, for a while already.
I prefer the new method though, but nice we have both now.
Edit: oops, FreeMind said it already.
I don’t want to see or work with the split/join widgets/“triangles”, so I’d prefer this to be removable in per user choice. And as I wrote earlier I’d like to, in preferences/whatever, also have the option to make the space type button to perish as it wastes horizontal space and causes the need for more scrolling to be performed.
