It would be great to let user fetch a branch that is not checkout'ed.

It is an important point to avoid unnecessary changes in your workspace files when you want to merge master into your checkouted branch and your local master is older than your checkouted branch.

Note that sometimes, changes in code may lead to long lasting rebuilds.

Right now, I manage to get this done with this workaround:

Opening console and writing:

git fetch origin master:master

But it would be great to have this functionality directly as a context menu option.
