It’s great to be able to register apps but using them leaves a lot to be desired. All of the apps including web sites lose state when you change tabs. So if you need to flip from planner to files then you lose your view and return to the default view in effect restarting planner.
This shortfall is even more obvious in files where if you need to copy links to an agenda in a web based CMS such as Confluence then every time you switch back to files it has returned to the top of any directory structure and you have to go back to the directory you were in to continue.
This largely makes the apps unusable apart from casual use and precludes teams from any serious use case intended to pull all your work into a single tabbed space. Even for basic sharing in meetings.
