Could the manual plugin placement be added as two shortcodes to the default plugin install? Currently I've installed the Shortcode Exec PHP plugin solely to have this made into a shortcode
Later on I'll be making a similar one for the most popular of all time. All this is done to avoid having allowing PHP in pages and to avoid having to do any file edits as they are more complicated to administer.
When the widget options are updated then these two shortcodes would be deprecated by one that takes options. Up until that they would rock and since then they could be allowed to function as they used to not force users to change settings due to a plugin update.
