Tower allows creating a new branch in a couple of ways.
Perform one of the following actions:
In the Sidebar drag and drop another local branch or tag on the "Branches" section header. The new branch will be based on the dragged item's commit.
In the Sidebar right-click on the "Branches" section header or click on the "plus" button at the bottom and select "Add New Local Branch...".
In the Commits "List" view right-click on a commit item and select "Create Branch from This Commit...".
In the Commits "List" drag and drop a commit on the "Branches" section header.
In the Commits "Recent" view or in a commit's details view click on the option gear button and select "Create Branch from This Commit...".
NOTE:When creating a new branch, if "/" is included as a seperating character in a branch name (or in a tag name) Tower will display this like a folder and allows easy grouping of branches.
