Allow to delete multiple branches at the same time

[Zuppremo]

Hi, I'm currently in my work project and doing some cleanup to the repo, I saw I can't select multiple branches to delete, and I thought that it would be nice if holding SHIFT + Left Click, allows me to select multiple branches and then right click delete branches (Or a shortcut like del), and a dialog box showing which branches are going to be deleted

An example what I say
