Today I came across a new article in XDA Developers where one of their members developed a new tool which is very helpful for beginners to develop their own ROMs. For now the tool is available on Linux only and the details of the features and how to install can be found here.
I will try to check it out myself and then share some screenshots and details about it. Please do try it out and you can also give suggestions and request features by posting it in their forum.
