Suggestion..................!
It's better to combine Extension Manager app along with the new GNOME shell Themes option to the GNOME Software.
Example:- Explore Installed Updates [Extensions] [Themes]
And also please add a repository management tool.
Example:- Enabling repositories [Check] Disabling repositories [Check] Adding repositories [Needed] Removing repositories [Needed] Customizing/Editing repositories [Needed] Multi-selection of repositories [Needed]
Editing comment and please fix the bugs which I am facing now during commenting.
Thank You
