For me the left side is very hard to read.

UTF-8 can be detected automatically, even without BOM. Could you please sketch how the encoding is configured in Eclipse, especially for all team-mates?

There only is whitespace below the last item in this tree control. If the repository has grown out of the starting state, there usually is no such whitespace.

Well, currently, we use the light-red color for modifications, the green (+) for addition and the light red (-) for removal. Changing something like this at this state of the application would mean that a VERY large number of users would have to learn new colors which could frustrate a major part of them.

"On the bottom Master is green, but changes to red at the top." This statement is wrong from the Git perspective, because master only is pointing now at the commit q. The commits a-h don't have anything todo with the named pointer "master". They could have been created with any branch, e.g. foobar, - this information is not stored in Git.
