Add filter to all sidebar widget content

[Jesper800]

I'm looking for opinions of other people here before proposing an approach for this.

What I'm missing, as far as widgets are concerned, is a filter for changing widget content. I would suggest something along the lines of a filter for the content in WP_Widget's display_callback method.

Using this, small changes could be made to widgets while still maintaining upgradability when the plugin, core or theme updates the widget — something that is not the case when extending the widget and overriding the widget method.

Hello Jesper800, thanks for the report.

Could you explain this a bit more? Which changes would you like to do?
Can't you use the widget_display_callback filter?

No activity in 7 months, and the widget_display_callback filter should suffice here.
