It should be possible to copy the second file and then invoke SmartSynchronize on the first file. In the occurring welcome dialog the copied file should be preselected in the second file input field.

Please add your wish as a different request. Thanks in advance.

Right-clicking a commit and selecting Edit Author is not sufficient to you?

What exactly do you want to see: a time stamp for each line or for each executed command? Time stamp or duration?

Well, for us, the toolbar belongs to the tabs.

A "view" consists of the tab and often also the toolbar area. Do you really suggest to group them together?

BTW, did you know you can switch between tabs using the scrollwheel of the mouse?

What SmartGit version you are using 18.2 or 19.1 preview?

Please give SmartGit 19.1 preview a try and invoke Help | Check for Latest Build to get #14054 which implements this feature.
