A small module that allows users to dublicate or make sticky the "Install" and "Uninstall" buttons under "admin/modules" location. Implemented using a List and a page_attachments_alter hook. Also a small settings section is located under "admin/config/user-interface/fastbuttons" on which the user can select the display option.
**Update 8/3/21
-An optional button for flushing the cache has been added. Enable it under admin/settings/.
-Some code rework. Mainly the JS files
Just place the module's directory under /yourproject/modules/custom/, install the module from "admin/modules" and you are ready to go!
This project may recieve some updates in the future to make it more functional and easy to use.
