There is a bug in Source tree 3.1.3 which was not in Version 3.1.2.
In version 3.1.2, I see on the top (in the tab) the name I gave the repository and I remember when I move mouse over the top, I could see the dirctory of this repository, but I'm not sure.
When I open a repository which is in a folder of sourcetree, after I opened it, I never see again where is the source of repository or whats the given name. The name which appers in the tab is the directory name.
With this bevhavior, the sourcetree will become absolutly unuseable because I never see, if I I opened the server repository or my workstation repository.
You have to change this immediatly, I will change to another software and I also decide to not buying your other products.
