Looking into the retro-future, newer smartphones or tablets allow the use of external mice. In iOS this feature came with 13, so I'm left out with my current hardware. Having an external mouse would be perfectly suited to work remotely using a VNC application.

My VNC app of choice is VNC Viewer, simply because my Raspberry Pi server, featuring Raspberry Pi OS, comes with it. However, not having a mouse kind of defeats the purpose of the user interface.
