When creating a new Feature (Gitflow), show me what last used names were

The purpose is to easily maintain a counter, like :

Feature-2017-05_my_feature

Then, when I'll create a new feature, whether this one has been closed or not, I'll know I'll have to name it Feature-2017-06_my_new_feature.

The same goes for releases (I name them Release-[number]) and hotfixes (Hotfix-[release_number]-[hotfix_number]).
