Separate teams/chat, calendar, calls, and files into separate executables
Having all of these disparate workflows, which are already largely independent of each other and only slightly interconnected, is needless bloat, wasting space when I only need to use one, and making things more difficult when I need to use more than one (eg. read a chat while in a call). It's like if Word, Powerpoint, and Excel all lived in one window and I couldn't look at more than one at the same time, but also had an always-visible sidebar telling me the others exist. These should be in separate executables.
