Focus #search-plugins automatically when visit plugin-install.php

[antondrob2]

When trying to install a plugin the administrator has to click "Add plugin" and manually focus the search input. This flow can be slightly easier if the users can start typing right away after they visit the page.

Add autofocus attribute to search-plugins input

Welcome to Trac! Thanks for the report and patch.

This has been discussed before in #29102, after the auto-focus was purposely removed, plus #39528 and #55267.

While many people want to search immediately by keyword, auto-focus would skip several controls (including the Upload Plugin link, about four links to browse featured/popular/favorite plugins, and the select element to search by author or tag instead of by keyword).

Besides, if you know the plugins you would search by name, you might prefer saving them to Favorites.

Thanks for the feedback. I'll search for existing tickets before creating a new one next time :)
