It is disappointing that once again MS makes changes to the user interface without options for the user to modify the module location. Having the nav bar on the left side has messed up my available space for other things I need to be viewing. Please give us the option to choose where we want it to be located! And of course, I would prefer to choose the items I want to appear. I don't need to see a bunch of icons for apps I do not need or want. As a long-time consumer of MS products, I am sad to see that MS appears to be moving Office 365 in the direction of cloud-based user interface without regard to the actual user's needs. My experience so far with Office365 vs. the Office desktop apps is the online version of the apps do not offer the same look, functionality nor features of the desktop version, and frankly, that is not acceptable! If you are going to push us in the cloud direction, you need to make sure that the cloud apps have the same functionality and features as the desktop versions. Otherwise, how are most of us able to do our jobs?
