Yesterday during a Build session, Microsoft software engineer Polita Paulus held a session on what it means for developers to upgrade their apps for Windows 8.1. While current Windows 8 apps will of course run just fine on 8.1, developers interested in taking advantage of the new code base will need to recompile their app and add or modify a few lines of code.
Like all OS updates, those of you who are straight up consumers just want to know, what does it mean for me? We know already that in 8.1 the “snap view” is basically gone in the sense that predefined sizes (1/3 or 2/3 of the display) are no longer required. That means you can drag and resize multiple “snapped” windows to whatever size you want.
