This extension is totally minimal. It will just clean the whole document from groups without content (dangling groups). That usually happens if you have a group but remove it's paths for example. The group will possibly stay in the XML tree. This also applies for layers because layers are just special types of groups.
This extension parses the selection and will put all elements into one single group. If you have a cluster with lots of groups and elements you will clean up this way (one top level group, all elements below it). If you select a single element or a set of elements you just wrap it like using CTRL + G (like making a usual group). You can also use this extension to filter out unwanted SVG elements at all. This tool is also able to drop elements with certain SVG tags to perform some kind of cleanup in the selection. You can drop elements like circle,ellipse,image,line,path,polyline,rect,text,tspan and some more. Notes: - includes "Remove Empty Groups" extension - includes "Apply Transformations" extension
