I can delete idea folder from repository. GUI is needed, because I and my friend are making some GUI tools, and next we will make an app, which will have all this GUI tools in one place. And our GUI tools are made especially for beginner Linux users, which can don't understand how to use commands, or they will not know nothing about functions of commands. It just don't have sense to post full app in one post, because if we will add next tools, we have to update our app. It's more clear, if we post separated GUI tools in single posts. And code must be simply, because it's open source project and I hope, that any person, which open repository to check the code will know everything about functions of this code in ready GUI tool. I hope that I explained well everything what you need.
