The diversity of Linux distributions is one of its strengths, but it can also be challenging for app and game development. Where do we need more standards? For example, package management, graphics APIs, or other aspects of the ecosystem? Would such increased standards encourage broader adoption of the Linux ecosystem by developers?
Small thing about filesystem dialogs. In file open/save dialogs some apps group directories at the top and others mix them in alphabetically with files. My preference is for them to be grouped, but being consistent either way would be nice.
