sticky_local_tasks
Provides more user-friendly, better, and fancier sticky local tasks.
There are times that whenever you are on a long page, you have to scroll up to the top of the page to access the local tasks that Drupal provides but this module makes a sticky icon on the bottom right of the page that holds all the local task items for easier access and with better UI.
Configurations
You can configure the local tasks to be shown on the bottom right, or the bottom left. Also possible to preserve the default local tasks and make duplicate sticky local tasks under /admin/config/user-interface/sticky-local-tasks
Similar/Insipiration
We already had a similar module called better local tasks, which didn't work at the time of publishing this module, so why this one? This one handles the UI and the logic a bit differently, with a lot of out-of-the-box icon support, configurations for the display, and more! There are some borrowed codes from there, so kudos to the devs there!
