What I miss is an app what installs and configures other apps. When I want to reinstall this is a lot of work, and when I have to configure many devices this is really much work. What I would like is an app what can produce some kind of configfile with a list of the apps what I use, and the configuration of these apps.
After this, the only thing I have to do while installing is to install this app, tell it where to find my configfile, and it does the rest. Finding the configfile could be automated too using DNS or something like that.
I would like a simple plain-text format, so that I can change the configuration for somebody else.
