+### Improve modularization of vorta source
+**Difficulty**: (Very) Hard<br />
+**Length**: 350 hours<br />
+**Skills required**: Python, software architecture, basic Qt<br />
+**Description**: The number of issues that are hard to solve because of flaws in the architecture of vorta's source code is growing. A overhaul of the architecture might be needed or at least extensive refactoring. This not an easy task. Besides requiring a lot of refactoring efford, it also requires getting a complete picture of the vorta code base. If you don't have experience and knowledge in software architecture you shouldn't choose to tackle this task.<br />
+**Task outline**:
+Delve deep into the source code.
+Create an overview over the current architecture.
+Identify architectural issues -- in regards to hard to solve bugs and feature requests also.
+Plan out the architectural changes needed.
+Refactor the code accordingly.<br />
