Here is the situation, you want to save some user preferences, for example, I like certain columns for a given table, I don't want to customize it every time, I'd like to save it. Originally, I thought I might need a configuration file to achieve this, but soon I realize that it would be a pain, first of all, where to put this file? if my application is achieved, I don't even have the access the application folder. Secondly, every time I update the file, I need search this file and remove the old entry. I think there got to be a better way to do this.
