 # TODO (Might be in order)
 1. MAKE IT BETTER  
-1. Ask if you want to update / manual update check  
+1. Manual update check   
-1. Show change log on update  
+1. Better AppImage integrations (Specifically updating, getting information from the appimage, and better appimage downloading)
-1. Better appimage support in general   
+1. Automagic appimage updating (It will of course ask you beforehand)
+1. Get information (such as name and icon) directly from an appimage
+1. Better appimage downloading (probably based around [AppImageHub](https://appimage.github.io/apps/))
+1. Sandboxing support  
 1. Check if all apps are closed when it closes and ask if you want to force stop the apps
