Hey @Matthias-Schaub ,
this looks good. I was struggling how to get these changes and the changes in the completeness branch together. I ended up copying most of your work and committing it into the completness branch.

Not sure if this was the best way to do it. 25ff666

What would be the best way to go on now? merge this into dev first and then the completeness branch? or double checking if these changes here in are correctly implemented in completness?

Hello @Hagellach37,

I would merge this pull request first, because it changes the underlying structur/names of project type classes.

After that one could merge from dev into completness and resolve conflicts there.

I imaging a lot of conflicts if one manuelly copies changes from one branch to another and then merges them. Git will not recognise same code lines and mark everything as conflict.

I could try to sort it out.
