Additional way to add plugin by indicating URL|slug of plugin page

[tobifjellner]

Today, when using the UI to add a new plugin, I only have two basic options.

• I may either upload the plugin as a zip-file, which somehow hasn't got into my behavior yet. (But soon may, if the issue described here doesn't get a nice solutuion.)
• Or I can search for Keyword|Author|Tag

I'd like to have a third way of finding the plugin. Reason is I may already know the exact plugin slug (or plugin URL).

One way might be to add one more option in the drop-down, to make it Keyword|Author|Tag|Plugin URL

And if the user selects the option Plugin URL, then we should disregard anything up to last occurrence of "/" and then use that last part as the plugin slug.

Even if I search for the full URL of the plugin Akismet, it doesn't reach page one today...
