Most meeting apps are built around sharing either the entire screen or a single app window. Sharing the entire screen means that everyone sees all apps, including your email, chat, and desktop notifications. If sharing from an ultrawide monitor, sharing the whole screen results in unreadable text for the viewers, and inevitably the question, "Can you zoom in on that???". While sharing a single app window is possible, it becomes a hassle when needing to share more than one app. This is because each time you switch, you have to stop and re-share the app window.
- Viewers may struggle to read a full ultrawide screen share
- You may not want to share your entire desktop
- Sharing a window becomes impractical when needing to switch between apps
- Resizing apps before every call interrupts your workflow
- You may want to hide unrelated areas of your screen
