> You can also manually tile windows. If there’s enough space, other windows are left in a mosaic layout. However, if there’s not enough space for this mosaic layout, you’re prompted to pick another window to tile alongside. Oooh, that’s going to be a usability problem, because it introduces a special mode for answering the “prompt”. Most users will never know that this mode exists, just that the system behaves weirdly and half-maximizes a single window sometimes. I see people today unknowingly or uncaringly invoking the window overview mode (sometimes called “Activities”), and then trying to, say, click a link in a visible browser window. They then become confused when the windows all zoom around, and the click they wanted is ignored.
