Naming of Documents Side by Side/Stacked
There is more than one way to interpret "Split Horizontal":
- Tiles stack on top of each other (the line that splits the documents is horizontally oriented)
- Tiles display side-by-side (the horizontal screen-space is split in two)
My expectation was the first option. Werner's expectation was apparently the second option.
According to Wikipedia naming of the tiling operation changed in Windows Vista to avoid use of the words "horizontal" and "vertical". Similar to Vista I recommend we use the following phrases:
Display > Documents Side by Side
Display > Documents Stacked
