Enable accessing commit content from the Journal view

Journal view is very convenient, but one important thing is missing in it - it doesn't show you the content of the commit. If you want to see what files a recent commit changed, I have to open a log view for this.

It would be great if we could have column in the Journal view telling us how many files each commit contains, and if I hover over it, it would show me a list of the first 10 files of this commit in a tooltip.

In addition, it would be great if the commit context menu would have a Show Changes menu item that will open diff of all the files in the commit (after the usual warning for diffing more than 3 files).
