I noticed that WebTop has in own category but Roundcube is in the Webmail category and no category about SOGo, but SOGo is mentioned in the WebTop category.
I think we need a category for SOGo. Also it might be better to put Roundcube in Roundcube category or in Roundcube/Webmail category, and not just Webmail.
Or can we place a category called Webmail with subcategories called WebTop, Roundcube and SOGo.
Something to think about.
