History window shouldn't prevent access to main window
While viewing the history log you can't go to the main SSMS window. This is an issue if you want to look at source code history side by side with another window.
As a workaround, you can launch another instance of SSMS. But generally, I agree, RG tools should work inside SSMS the way other SSMS tools work -- modeless
I agree. Modal focus on this window makes it difficult to use.
