**Description of my planned/completed work for the project:**
After communication in issue tracker was decided to create an option in menu with show a window for color modification.
+
* I tried to check a project structure.
+
* I found and added new option into menu.
+
* I can not find a definition of already existing "Options" window. I also can not find text used in this window due to many language mutations.
+
* My friend who works with C++ and Qt wasn't able to find another window definition as well.
+
* I tried to read something about HWND and graphics in C++ for Windows, but I realized that modification by total C++ beginner could do more harm than good for Sumatra project.
+
* I apologized to Sumatra community..
**Conclusion**
+
It is not a good idea to try to add feature into huge project which is in totally different language than I can use.
