Add 'All Sites' to the Sharepoint Tile landing page (aka /_layouts/15/sharepoint.aspx)
Right now, when my users click the SharePoint Tile in O365, They are met with a page listing 'News from sites', 'Frequent Sites' and 'Suggested Site'.
Given users end up as members of multiple sites, it can get hard to keep it all organized. What would be great would be an addition to the three sections described above that will list 'All Sites' that a user has access to. That way end users can find something they use sporadically without having to remember some part of the name to do the search...
