Hover over a Jira task title to generate a Git branch name, then copy it to clipboard.
For *.atlassian.net sites, namely Jira, you simply hover over the task's title, and a popup will open just below, and in this container there will be a select element (where you can choose from "feature" <- default, "bugfix", "hotfix"), a checkbox (whether to use the task number or not - checked by default), a Copy and Close buttons, and an editable input field for previewing what exactly will be copied.
It respects the theme set by Atlassian (dark/light mode).
