Long (GIT) tag/branch names are shortened and unreadable

I've just updated to the new Mac version of SourceTree.

Now on the sidebar tag and branch name are shortened (using ...) if too long, even if I enlarge the sidebar. Thus things like minibems-ws-server-0_3_24 and minibems-ws-server-0_3_25 are both displayed as minibems-ws-server-... making impossible to distinguish them.

Please switch back to the previous visualisation that was better. This new one is unusable.
