For the desktop Teams application, it would really be helpful to have a personal preferences menu so that that users can set defaults for certain tasks or views. For instance, I would much rather be able to use a Preferences section to set a default rule for opening files within their native desktop applications. Opening files within teams is slow and clunky, and the application features are limited compared to the desktop application. If I could easily double-click on a file and have it automatically open up within the file's native desktop application (Excel, PPT, Word, etc.)...that would be awesome.
