I recently found about about this cool app (https://www.unifiedremote.com/) (along with its companion PC server software) that lets you control your PC from a tablet or phone. It's a great use for an old tablet so dust it off and check it out. This software was inspired by this ComputerWorld article. (https://app.getpocket.com/read/2743315183)
If confirmed, I will demonstrate this at the October PLUG meeting. See here about the upcoming meeting suggestions and comments. (https://forums.plugintolinux.ca/index.php/topic,879.0.html)
