We have SharePoint Online and we are creating some site collection and adding subsites then when we realize that we need to active a feature per site we need to go site by site to do this activation, kind of painful.
I was wondering if do you know any tool where we can manage this active/deactive site features?
that would be great to have a central tool to manage the site features.
So sorry. Should have read more carefully. The only way I can think of for SharePoint online is to use the SharePoint Online Management Shell along with these extensions by Gary Lapointe:

My apologies I didn’t have a better answer and hope the above will be of help!
Thanks!
