I am using brief style window splitting using create-tile with cursor keys used to select the split direction, but am finding that the beta is automatically resizing windows when I create and remove splits.
When I split a window, I would like it to split the current window in half and leave all of the other windows alone so that I can manage the sizes of the windows. What I am seeing is that sometimes the windows are resized so that they are evenly spaced, and that at other times small windows are created with the size being stolen from the left most window.
Similarly, when removing a split, I would like the surviving window to expand to occupy the space of its removed sibling. What seems to happen, in the case of vertical splits, is that the surviving window keeps its size, with the width of the removed sibling being added to the left most window.
The unpredictable automatic sizing behaviour, together with flashes of background appearing when the rightmost (vertical split) window is removed before the other windows are redrawn make for a very unstable and distracting experience.
I'd *really* like to see splitting behave in the same stable and predictable way as in previous versions.
